This product has great fit and are very comfortable.  Great for leisurely snorkeling but does not help with blisters while swimming laps in the gym.  Product only protects against blisters for about 30 min while doing laps.  Not suffiecient for my needs but will probably be satisfactory for less intense swimmers.

Title says solid beach sock.  Well Its a fit flimsy...like a low cut loose sock.   EVERTHING can get caught in there sand, stones, and shells.  Has no use at all on the beach.   Maybe the boardwalk....hummmm   nope...not even there

I ordered a size larger and they worked really well.

Very comfortable and they even stay on in the water..

Got these in a x-small; my wife is a 6.5 and they were too small. Returned them for a size Small(6.5-8.5) and they fit perfect. So, yeah, they run VERY small! The material stretches but the actual size of the foot pad is what makes it feel too small.

Eases the walk on less than sandy beaches.
