The bottom sole is as durable if not more than a shoe there is very little flex but it is very well secured to the fin again very durable. I wish this maker had medium size and long size fins.

Soft and comfortable, yet with an adjustable strap to secure them. The only thing not great about them is their buoyancy. They are very very comfortable and buoyant though.

Comfortable, secure, easy to walk on - perfection. The neoprene is not too tight or sticky to get on, but keeps suctions down for a good fit.

The design is amazing. Everything about this product works perfectly for her needs. Very good invention.

Ruined our trip to hawaii.

Freediving requires that you expend minimal effort. There are hook&loop (velco) straps, that unfastened every time i was in the water. The fin blade is very rigid, and it is set at the wrong angle.

The soft fabric part rubs against the heels causing blisters. The one i got seemed to have been sized for a woman's foot and thus too narrow.
