I purchased this for my fiancee who was a ring size 5.5 on one hand and a ring size 6 on the other hand, so figuring out which aqua knuckle size to purchase was a bit of challenge as her hands were split between the aqua knuckle size 4s and 6s. However, John was very helpful with providing guidance and the size 6s were indeed the correct fit.
So far, the aqua knuckles are holding up very well and the pouches look and feel very nice.

I am a ring size 8.5 and the aqua knuckles size 8s fit both my hands perfectly. Very sleek design and much lower profile compared to wearing paddles for hands.
After wearing them a few times, I definitely feel like I am pulling more water with each stroke, especially when swimming butterfly.
John was very helpful in answering my questions on sizing. My package had to travel a pretty far way to get to Toronto, Canada but arrived in the mail in good shape.

A easy way to get a proper finder spread feel of the water. Another useful pierce of equipment to add to your swim bag.

A creative training tool! I appreciate the promotion through MySwimPro and I am feeling a difference in my pull since incorporating it into workouts!
Alberto B.
They are great
Very helpfull

I am retired college and club team coach. In retirement I am doing a little coaching of triathlete and masters swimmers online and am training myself. I tested the DUBL wide knuckles on myself and it took a set of 16x100s for it to really sink in. When I took them off for some fast repeats my hold on the water felt amazing. My training partners borrowed them and felt the same thing. Great product !
Amy Z.
I absolutely love my aqua knuckles! They’re easy to wear, comfortable, and reinforce best practices while swimming. They’re my set-and-forget game changer. BUY THEM fellow swimmers.
Christopher B.
easy to use
works as described

Great for amateur swimmers! Thank you so much for this product)
Justin M.
A nice and straight forward approach to aid in finger spacing.
Mary G.
I realized I was keeping my fingers too tight and stiff when swimming and this agitated my arthritis in my hands. Using the knuckles has almost eliminated any finger pain. So happy I found them. Won’t swim without them again!
Rob F.
Getting fingers to separate optimally is not the most natural part of advanced swimming technique. The Double Wides are an innovative way to train the ganglia in the hand/forearm to space the fingers automatically after practicing with them.
Jim S.
As an age group triathlete, I am always looking for a way to improve. Looking at some of the YouTube videos on the concept of vortexes created around each finger that increases the pulling area of your stroke made sense to me. I measured my fingers and found out that I was an in between 12.5 and that left me deciding on whether or not to get the size 12 or 13 aqua knuckle. I went with the 12 which seems to fit fairly well when pushed to the base of my fingers. One problem which shows in the photos is that two fingers seem to have a good spread, but one finger still touches the other finger, even with the aqua knuckles on, since there was not sufficient rubber to push them apart. I have tried wearing them on my knuckles, which gives me a greater spread as shown in the second photo, which may be too much spread and the size 12 fit pretty tight when on the knuckles and not the base of the fingers. A little more rubber would give that fouching finger the spread it needs.

Appreciated the good customer service and getting the fit right on the Aqua Knuckles. They work great and help me improve my technique.
Drohan A.
Great company to work with! Helped out so much with sizing and hopefully we'll see great results with their usage!
Alison J.
Excellent customer service! Great product for technique junkies! I’ve just gotten back into swimming and always like to improve technique. These are a great tool to keep your workouts fun, and never get bored!
I was unsure which size I should get to put over my wedding ring and they added two different sizes for me to try! Email responses and prompt service would make me highly recommend Aqua knuckles!
I’m already recognizing that I have lots to improve with this great tool.

Comfortable and works as advertised

These are interesting.
Johnny L.
One of the best buys to get the correct finger position easier than paddles. Makes a great variety for swimming
David G.
It is an amazing product that we use a lot in swim practices and it has helped me improve on getting a more powerful catch. The aqua knuckles are comfortable and with the proper size they can help perfect your finger spacing while swimming. Must try product!!!
Darren A.
They fit quite well and don't feel like they would come off at any stage. The sizing chart is a bit difficult to get right. As for performance improvement that is still yet to be determined. We have only had them a few weeks but its definitely worth something.
sherie s.
Love Aqua Knuckles. I find they work especially well as a more shoulder friendly training tool than paddles.
Jeffery S.
Fit well and have really helped my daughter with finger positioning!
greg M.
I tried the aqua knuckles for the first time during one of my sets last week. Didn't even notice that I had them on. They worked excellent keeping my fingers evenly spaced. Two thumbs up!
Michael S.
Seems to work. Too early to know.
Eric L.
Really great idea. My coach had been trying to get my finger spacing more even. Frustrated but when I found your product boom it made it much more effortless. Thanks.

I definitely can feel a difference when using this perfect little green helper.
Besides of swimming, I'm using it also for aqua jogging.
Sharon B.
They work as advertised. Muscle memory works!
Sebastian S.
To be honest, I use them the other way around than I thought. I have a "Spock" in my team who keeps his fingers grotesquely far apart when pulling his arm. That's no longer possible with the things! Tape would also go, but then he would have them too tight, then you would have a problem with a problem replaced.
Joshua U.
feels more natural compare to using paddle. i am going to use it more often when swimming. for us Asian thsi Aqua Knuckle is consider Expensive however it is worthy
René J.
It’a great
Greg C.
The best product and best customer support you can possibly imagine. I highly recommend aquaknuckles.
Cathy T.
Excellent company, sent me a smaller pair at no cost! Using them 3-4 times a week and I have seen an improvement in my freestyle stroke, love your products
Cathy T.
I think i swim a little faster, they are a little loose especially on my right hand, not sure exactly how they will help me.
Jennafer M.
Ordering was easy, received the product quickly. Great quality product and service.
Jamie S.
I contacted the owner to figure out what size to get my son and I had to order before he got back to me. He sent the bigger size free of charge just in case. My son’s entire national team uses these in training. Great product and even better service!
Queenie D.
The first 50 meters of use can be a little overwhelmed. But after 200 meters, I found that my palms would relax, the water in my arms felt much better, and I doing catch the and push the water smoothly.
Valerie G.
Excellent experience ordering the aqua knuckles. The size we ordered was incorrect and they sent out a bigger size very quickly with no questions asked.
TYANNE C.
My swimmer loves this training aid and highly recommends especially for distance training

I just received my Aqua Knuckles. The fit was perfect. I’m a 60-year-old beginner swimmer. My first lesson was a disaster as I looked like I was violently drowning in a 5-foot deep pool. I kept at it and now swim 4 to 5 times a week for an hour. I’ve improved a lot over the last couple months but I’ve become too reliant on hand paddles. When swimming barehanded I slow significantly and become exhausted quickly. I’m swimming for weight loss and I’ve dropped 110 lbs thus far. Did I mention I only have 1 lung? I needed to break this habit but my hands keep cupping. I saw the Aqua Knuckles on MySwimPro and thought I’d give it a try. I’m not trying to shave seconds off my time, I’m just trying to swim normally and gain endurance. I swam with them for the first time last night. It was an instant game changer for me. I swam 1,000 yards in 30 minutes! Plus, I was able to do that swimming all 50’s which is something I’ve not been able to sustain. I know to you seasoned swimmers 1k in 30 minutes will get you kicked off the team but to me it was a major accomplishment and was completely unexpected. My goal has been to join Pre-Masters and then, Masters swimming. You’ve made that possible for me as I cannot rely on those paddles to get me there. Swimming has literally been a lifesaver for me. Thanks so much for making those little chunks of rubber that make such a huge difference. They’re amazing.
Rosa E.
The owner is very attentive and cares about his/her customers. I am pleased with the product. Despite of the fact, my daughter has not used them I believe it will help her a lot.
She started swimming yesterday and the coach approved them to use during practice.
Douglas M.
I tried my new aqua knuckles for the first time today. The difference is subtle but significant. They are a helpful feedback tool and good for training. I will be interested to see how long it takes to re-program old neuromuscular habits.
Chris P.
While swimming laps, many people have inquired and i gladly share and recommend going online and placing an order. Thank you
Autumn S.
I’m just getting started! I’ve only used them a few times. So far I’ve really enjoyed them.
Lothar M.
These Aqua Knuckles have completely change my approach to swimming. I feel fitter after using them in the pool.
Lothar M.
I was flopping around in the pool and continually changing my swim techniques ongoing. At the end of each I still felt that I was lumbering in the water with lots of effort poor results. I found the Aqua Knuckles on utube. Listened to the video and I was sold. After getting used to the feeling of the AKs the results have changed my results, more speed less effort, I actually feel better after my swims with renewed energy for my efforts. Great innovation.
Tanya P.
Disappointed to not get a matching bag colour. I chose the green knuckles to be visible in my blue kit bag but they came in a blue bag.
Glauco S.
Great quality and fantastic Customer Service!
Chad S.
Aqua knuckles have been a great training aid. I swim about 1500m with them each day. It has really helped me swim with a more relaxed and open hand and pull more water with each stroke. I would definitely recommend.
Rick P.
I originally ordered a pair about a month ago. I had a little trouble figuring out the correct size at first and mentioned I would likely purchase a second pair because the original pair was just a tiny bit lose in the water. To my surprise and delight I was shipped the correct size based on my first review. The new pair fits like a glove and don’t have that little bit of movement when in the water. I love them and have noticed a difference right away, shaving a few minutes off my normal swim time. I don’t swim for time, more for the workout, but am enjoying the little bit of extra power I get from using Aqua Knuckles. It has been a great pleasure dealing with the makers and will promote them at my fitness centre. Thanks for the good will to fit me appropriately. It is greatly appreciated.
mr c.
These have really improved my feel of the water and catch phase. They are comfortable, easy to use, and have a cool storage case. Great product and support. Thank you.
Thomas S.
I’ve never paid much attention to my finger positions when I swim. So when my friend showed me the link for the Aqua Knuckles I thought it might help me swim faster. Then I swam the next day before the order arrived and realized that I already swim with my fingers apart. So I thought, well, this is a waste. But NO! I got the order and started wearing them. I’ve shaved 1.5 minutes off my mile time! I’m invigorated and doing some HIIT laps. Thanks!!
Dexter G.
A little snug but would like to try larger size..
Rick P.
Great, speedy shipment that was well updated on its travels. I had a little trouble with the sizing; I would probably benefit from the next size down, but they are a good enough fit from the instructions. Time will tell after using them in the pool for the first few times. Would order another pair without hesitation in a smaller size if need be and use the ones I have as a very good backup.
Lauren M.
I finally got to used them in the water with both of my age group swimmers, it really helped with their finger position, sometimes they open their fingers too much, or too closed. Great product!
Janetta H.
Good quality!
Jad K.
I followed the sizing chart but the ones that arrived are too big and soft rubber
So waste of money as they can’t be used
Maureen W K.
Great aid in helping me learn the more proper separation of my fingers to improve my swimming technique. I’m not a competitive swimmer & I’m an older (70 yrs) advanced beginner-intermediate type so I wasn’t sure if these would help me. THEY ARE HELPFUL.
Bruce K.
I really love using the Aqua Knuckles for training. They have helped my swim workouts tremendously.
Damon A.
It was interesting to use at first but easily to get accustomed to. They work great in helping with all strokes!
Thomas L.
Perfect
bhakti c.
I love these! Was having trouble with hand paddles as they would cause shoulder stuff.
The aqua knuckles are perfect! Form feels better and no shoulder issues.
Highly recommend for masters swimmers.
Brian P.
My swimmers love them and can feel a difference in the amount of water that they can pull immediately! It is rare in swimming to have instant improvement in anything. These do just that!
Dee A.
I actually really like these, they are comfortable to wear and definitely giving me more propulsion!
I’d recommend!
Javier B.
Great purchase. Overall process: buying, shipping and delivery was good.
Pascal B.
Used it few times
Had to use the smaller size as it felt more comfortable and felt easy
SAMSIC E.
excellent product tested during several training sessions. rather effective for the grip in freestyl and backstrock. I recommend ... great product.
Suzan B.
I am a multi sport coach and am always looking for tools to help learning swimmers get a better feel of the water. I find that these a bit like occupational therapy for swimming and are a positive addition to my toolbox.
Lannie E.
They really help the form of the hand which helps the entry.
Andrew E.
Original shipment got lost and never arrived. Emailed and received a quick response that a replacement was sent at no cost and I received it. They’re a really neat and innovative item!
Michael M.
i really do fell like I'm covering more distance in less effort
Jennifer D.
I bought 4 pair for me and my swim buddies. So far I think they are great. It adds a little fun to my workout.
Leonardo C.
Great feel and they fit super nice and snugly!!
Super product I love them!
p.s: For those who are willing a feedback on the color, the green ones are not teal but rather a more normal or 'electric' green.
KATHY H.
Took a chance and ordered this. You won't know that you need this until you actually swim with them! Besides helping with my feel for the water, it is helping me remember to point my fingers downward during the catch. Kathy Haeria
Patrick H.
Nice Equipment
Anthony Q.
It's true, you feel a speed gain in your swim ! I recommend the aqua knuckles, very good item !
gabriela g.
My 12 yr old daughter, loves the knuckles, she had some issues with her hand and fingers during pulling on how tight or how open her hands should be, but with the help of the knuckles it helped her to have better feel for the water and she finally see improvements in her pull.
George K.
Made a difference in my lap times,
Keith R.
does exactly what it promises: perfect form. now for the rest . . .
fred m.
Just enough propulsion. Much better than paddles and easier on shoulders. Good training tool for tempo and finger technique.
fred k.
Great experience and customer service.
graham f.
Works as advertised. Not game changing to my stroke, but helpful addition to the workout routine.
David H.
I was very disappointed with these. I found them to be uncomfortable and after using them, I found it really easy to keep my fingers slightly separated without them.
fred k.
Great service. Thank you.
I ordered the wrong size and they replaced with the correct size without any issues.
Much appreciated.
Heath T.
The science behind this product has been known in the swimming community, and utilized, for years. However, there aren't very many products that allow for proper training of hand placement and finger spacing to truly gain the necessary muscle memory for a proper training response. The aqua knuckles are a game changer! Not only can you use them for drilling/skilling sets at low speeds, you can also utilize them at higher speeds. This is extremely beneficial. It allows your body to adjust to the proper feel at various points in your stroke when swimming at race pace.
Honestly, after using them for the first time, I actually felt withdrawal symptoms from my hands when I took them off to continue my practice. I had to chuckle, because it was so effective and my body noticed a positive difference so quickly. I would highly recommend this product to anyone that is looking to improve their stroke efficiency
Matthew C.
Works well for warm ups and drills. Overall has given me a better feel for the water.
Gary B.
Just swam 4 miles with them and no negative issues
Gary B.
Great training item. Was keeping my fingers together for over 20 years of swimming before I discovered they should be apart. Needless to say, trying to break a 20 year habit is not easy but these “simple” items do the trick. LOVE them.
Tony C.
So far so good, I have been trying to cut corners for ages so if Aquaknuckles help me find that little extra in using water in a more efficient way then I am all for them. Nothing ventured nothing gained. They fit nicely and I can certainly feel a difference in my arm action. Aquaknuckles remind me a little of using paddles but scaled down. Using Aquaknuckles on fly was a strange feeling and effect, I will have to work with them a little more. As a 65 year old and a Masters swimmer, swimming innovations are still there to be found. Try a pair of Aquaknuckles, I don't expect miracles but any improvement aid is always a welcome addition to my set's. The whole Aquaknuckles package is a quality item and communication is spot on. Seriously, what are you waiting for?
Chris P.
I'm just learning how to swim efficiently: breathing, kicking, catch and pull, the whole nine. The aqua knuckles allow me to spread my fingers just right w/o having to think about it. I'm smoother in the water.
Carmen V.
I won't take them off!
Terri M.
The swimmers enjoyed trying something new. They liked being able to pick their colors. Any suggestions for training would be welcomed!
John S.
I use the great Aquaknuckles regularly in my training. I alternate wearing them in sets, as I focus on my stroke technique. Comfortable and easy to wear, they bring a new awareness of hand and finger movement in the water. I highly recommend to experienced and newbie swimmers interested in improving their stroke, speed and fun in the water.
Anthony P.
I have found the aqua knuckles to be a useful training tool in my swim bag. I do at least one set with them every workout!
Nikica S.
