Flippers perfect for snorkeling

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 😃

Small and stiff...

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.

Snorkeling fins

Very compact, but not able to propel well in open waters swim

icon-circle-checkmark verified purchase
Adjustable fin

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
