U.S. Divers Hydrosplit Fin (Large/X-Large, 9-13

The strap is no good compared to a boot fit fin and can become irritating. they only allow a certain level of thrust before you are just waisting energy (not made for hard thrusts or fast swimming). OK for training fins or minimal usage. The best fitting fins are the ones without straps, just get 1 size smaller that land shoes so they fit snug and don't chafe yout heels.

I found these fins very comfortable for snorkeling. They fit well even without diving boots. They are actually better without them, as they tend to be a little tight if you wear boots.

I used these fins to go snorkeling in Hawaii and my feet never cramped up and never hurt from these fins. Dive boots are not needed. These fins are a great workout for your legs as well.

Unless you were size 9 or less do not order these. I were 11 and they barely fit without boots, if i put on the boots i can't feet even my fingers in them

I use the fins every day to swim laps at our local pool, and in one month have seen a big change in the tone of my legs. I really like the open heel on the fins and would buy this product again.
