Product Customer Reviews

These are super easy to put on and they are nice and comfortable
Bit tight across top of arach but fine otherwise.
Easy to put on, although slightly tricky to pull the rubber heel tight enough to then secure it in the hole you want, however easy if someone there to help you. Very neat to pack in a case so highly recommend for hols as they may not be long enough for a pro but perfect for holiday snorkelling 😃
Great in the pool.
Brought for pool to strengthen my knee
Helps swim faster
Nice intermediate swimming aid between bare feet and full fins. I like them

I was not expecting it to be very short & very small, considering it's already a size large. I suggest you go straight for the usual fins.
Very compact, but not able to propel well in open waters swim
Fin is easy to fit but not easy to adjust. It could be better if the fin is more flex. Otherwise ok for this price
