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.
Trenton Julian is a member of the 2022 USA World Championship Swim Team and the 2022-2023 USA Swimming National Team. He is a member of the Mission Viejo Nadadores Pro Group. At the 2022 World Aquatics Championship in Budapest, Trenton won a gold medal in the 4×200 meter freestyle relay and a silver medal in the 4×100 meter medley relay. He helped the USA defeat Australia in 2022’s Duel in the Pool with a gold medal in the mystery 200IM and dominated the 200m butterfly for the win at Australian Short Course Championships in August, 2022. Trenton was a key swimmer on Cal’s 2022 NCAA DI Men’s Swimming & Diving Championship team in March, 2022, where he was a gold medalist as a member of the 400 medley relay. In 2021, Trenton became a World Champion and American record holder as a member of the 800 free relay representing Team USA at the 2021 FINA Short-Course World Championships in December 2021 in Abu Dhabi. He is an 18x All American and was an integral member of the Cal Men’s swim team throughout his college career.

Open Finger Training
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.
