Our flagship product, the DUBL WIDE, will help you develop muscle memory in order to train yourself into better open-finger technique. Wearing the DUBL WIDE as little as a few times per practice will give you the feeling of proper finger separation. As some of the fastest swimmers in the world already know, having your fingers slightly separated increases your hand surface area up to 10%. What does this mean? It means your human paddles just got a whole lot bigger. This is going to let you pull through the water considerably faster – and get you to the wall ahead of your competitors. Studies have suggested that open-finger swimming can shave off .5 seconds per 50 yards. Aqua Knuckles mean faster swim times for you and your teammates.
Aqua Knuckles is proud to announce a NIL partnership with Trenton Julian, member of the USA Swimming National Team and Cal Men’s Swim Team. Aqua Knuckles are new and innovative training aids worn by competitive swimmers to develop open-finger technique muscle memory to generate a more powerful pull. Aqua Knuckles is utilized by swimmers at every level worldwide.

“…having Aqua Knuckles on creates that constant reminder of the best hand and finger placement” Trenton Julian
Not too long ago, our observant Founder started noticing the fastest swimmers in the world swim with their fingers slightly open. After extensive research and field testing with competitive swimmers, the first set of Aqua Knuckles™️ was born in Los Angeles (2018). Aqua Knuckles™️ are a matching pair of silicone bands you slip on the ring and middle fingers of both hands. These bands space your fingers 5mm apart – giving you the best open-finger positioning for better technique.
