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.

Customer Reviews

First experience: Exactly what I needed
Product Rating
by Bart
Ordered the fins in medium/hard with Pathos footpockets. Took a while to arrive but that is what you'd expect from custom made products. Along the line all questions about status were answered and when shipped, you are well posted. Packaged very firmly and arrived without damage.

About the fins:
Good build quality and for my weight (100kg) and length (200cm) the correct stiffness. They provide the correct amount of thrust without bending too much. The Pathos footpockets Have the correct length in accordance with the size tables. They are a bit wide though so I will try them with socks on to see whether the fit will be a bit more snug. Unfortunately we have to wait for the pools to reopen after the pandemic will be under control again.

Easy order process, sizing of the footbeds was a bit tricky. They were a little larger than expected. Nothing a thicker booty can't handle. The material is excellent. The time between order and shipment is slow and there is not much communication as to status. So be prepared to wait a while (weeks) before the order ships.
