Speedo Biofuse Fitness Fin

— Show original

Surprisingly small size classification, but the flipper does not squeeze. A good technical fin, the small size of course does not give much help for speed.

They are good, they strengthen the leg muscles. Also suitable for people with arthritis. There is also room for Vaivasenluu.

My shoe size is 43 and these flippers are just right for my foot. When I put the flippers on, they feel a bit loose on the feet on land, and a finger can easily fit between the heel strap and the foot, but in the water they don't slouch at all. These kind of looser-feeling flippers suit me better, as sometimes I've also had really tight flippers and they started to squeeze my legs while swimming. Good product for me!

Works well and fits well

I had to return it because the size was not suitable. It squeezed, but the next size felt too big when I tried it on in the store. Otherwise, definitely a valid product, if it happens to fit.
