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.
