Our foot pocket sizing is true to actual foot size in millimeters / inch. 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.

The WaterWay Powerfins 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.

We advise selecting blade stiffness in correlation with your overall weight and physique;

• Stiffness 1 - Extra soft - Weight under 45kg (~100 lbs).
• Stiffness 2 - Soft - Weight between 45~70 kg (100~155 lbs).
• Stiffness 3 - Medium Soft - Weight between 70~90 kg (155~200 lbs).
• Stiffness 4 - Medium - Weight between 90~115 kg (200~255 lbs).
• Stiffness 5 - Medium Hard - Weight over 115kg (255 lbs).

In order to correctly measure the length of your foot, please follow the measuring guide in the illustration below. Foot measurements should be made while standing on your feet on a flat surface.
