Force Fin Shoe Size Conversion Chart

Instructions:
Adjust up or down a size for very wide or narrow feet.
Adjust up a size if you have a high instep. Force Fin® foot pockets fit around your foot. Shoe width is more important than length. And whether you were barefoot, with a Comfort Instep, low-profile or bootie with a heavy sole also affects size. If you want variability try one of our Adjustable Foot Pocket models that fit a range of sizes.
