These little kickers are designed specifically for bodysurfing and damn do they work well. The blade is a perfect size and has a great flex for quick sprints. In addition, the fins have little built-in vertical blades to help stabilize the fins and keep you in the pocket. Hands down the best bodysurfing fins out there. These fins run really small, so you might consider ordering a size up. The sizing is (in mens): XXS 1-2, XS 3-4, S 5-6, M 7-8,
