The Freestyler Hand Paddles from Finis are a swim training tool specifically designed for freestyle swim training. They are shaped like a fin and help you to achieve a strong pull through, improved rotation of your hips and increased stroke efficiency. The finger strap is adjustable to give you a perfect fit and the narrow design will prevent shoulder strain.
Great "pieces of kit"! Just what's needed to make sure that I'm getting my stroke right.
I am using these as part of Swimsmooth technique development, they do make you think about your hand position and exit angle.
