The Finis Agility Paddles teach swimmers of all ages the correct hand position when doing all four strokes, an incorrect hand position will cause the Agility paddle to simply fall off.
This hand paddle is a great tool for recreational swimmers as well as club swimmers to improve their "catch" of the water which will enable them to swim further and faster. It also creates resistance in the water which will build upper body strength when used regularly.
Slightly overpriced for what they are. Competitively priced by SS though.
