Product Questions

Do foot pockets run large or small compared to actual shoe size?

Our foot pocket sizing is true to actual foot size. For use with up to 3mm neoprene socks we advise selecting the foot pocket size which corresponds with your actual shoe size.

For use with thicker (5mm+) neoprene socks, we advise selecting one size larger than your actual shoe size.

To determine which foot pocket size is right for you, please refer to our universal shoe size conversion chart.

What's the difference between Classic and Lite Footpockets?

Ultrafins are available with two foot pocket designs; Classic (with full rails) and Lite (rail-less);

Lite foot pockets reduce the total weight of each fin by ~150-180 gr (depending on foot pocket size) without compromising the performance of the fins.

This is really a matter of personal preference; some divers prefer heavier fins while others prefer lighter fins.
