Price is for a pair of blades, and pathos foot pockets assembled ready to go
This is the new upgraded K8!  The K8 S Pure Carbon.  We have worked with Carbon experts Soriatec to produce a seriously powerful and reactive pair of fins.
The blades feature 'Dual System', which is a smooth surface on the front and a matt finish on the back.  This improves thrust and overall performance/efficency.
The carbon used is 100% pure carbon and of the highest quality, using the latest technology and machinery.

All manufactured in Europe (Spain).

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 one of lightest full foot pockets on the market, and are really comfortable (Can even be warmed up to mould to your feet!)


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) - 24cms

Blade length (no foot pocket) - 50 cms

We reccommend wearing these fins with a thin neoprene sock

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