Current Stock:

Using many years of experience and testing (some of the best players in the UK) we have produced the lightest full foot pocket carbon fin available for Underwater Hockey.  Using the same methodology as our Freediving/Spearfishing 'Pure Evolution' (used by top Spearfishermen/Freedivers in the world) we have been able to produce a powerful, reactive, balanced and light fin for the most demanding player.

Carbon blades made to the highest standard, to ensure ultimate power and reactivity.

T shaped edging to help the flow of water to remain straight along the blade on both the up and down kick, so maximises efficiency.

Pathos foot pockets are used worldwide to compliment the best blades.  They are lightest full foot pockets on the market, and are really comfortable (now in standard and soft).


Weight of each fin - 650 Grams (1.3kg total) - Based on 38-40 foot pocket

Full length including foot pocket (38-40) - 62cms

Blade Width (widest point) - 23cms

Blade length (no foot pocket) - 48.5cms

We reccommend wearing these fins with a 3mm/thin neoprene sock

    The most comfortable fins I've worn in a very long time without compromising on speed or power.
