When you swim with your fingers slightly spread, you improve the force you can produce with your pull and you swim faster. Your pull becomes more powerful and you pull more water. The water around your fingers moves with your hand and simulates bigger hands. In essence, your slightly spread fingers and the water around them create a webbing effect in order to give you human paddles.

When most of us were taught how to swim, we were told to tightly close our fingers as we moved through the water. Competitive swimmers want to get through the water as fast as possible. If you slightly spread your fingers, you will get to the wall faster. It’s very tough for swimmers to break the “tightly closed fingers” habit…whether they’re seven or seventy. Aqua Knuckles helps swimmers create muscle memory for open finger swimming.
