Hopefully with better hydration and increased physical fitness your cramps will be a thing of the past, but something to consider is the below test. It can be a real eye opener!
Try this simple test to see the difference between how Force Fins work with your body as compared to other brands. While seated, cross your ankle over your knee, grab your toes and pull them in the direction of the sole of your foot.
Do you feel the stretch and tension running from the top of your foot up and along the shin? Those are the primary muscles that other fins work because the fin blade extends from your toes.
Now, hold the top of the foot - pull again toward the sole of the foot and resist with the leg. The tension has moved up to the upper leg, hasn't it?Because of their unique design based on human biomechanics, Force Fins work the larger muscles of the upper leg in addition to the lower leg. These muscle groups are large and powerful. They are best equipped to efficiently power your fin blade.
