Swimmers and coaches know that foot flippers change the kick actions for freestyle, fly and backstroke. Foot flippers use different muscle actions and stress the smaller muscles in your feet and ankles. Holding foot flippers in position also strains your calf muscles. Foot flippers are not adjustable to match your kick.
