Can one pair of fins have it all?
Introducing the Vertical Blue
B L A C K F I N
Designed according to the stringent specifications of Team Vertical Blue, these are the most precisely engineered blades on the market, combining:
– 3D-Dive® - the first fin to use this patented technology, that uses a gradient of 27–30º in inclination between the inside and outside of the blade, in order to prevent external rotation
– asymmetrical anterior edge to avoid fin contact
– featherlight carbon fibre for a weight of just 300g per blade
– world's most comfortable foot pocket (Seac), adjusted in factory for high-performance
“The Blackfin provides consistent power, perfectly balanced between both phases (forwards and backwards) of the finstroke. This means the legs work continuously, but at a lesser force compared to most other fins, where the force required fluctuates up and down.
The effect is that an ascent seems like it's chopped in half: after a short period of fin cycles you're already hitting the surface wondering where the depth went! It's only when you look at your gauge afterwards and realise that those leisurely finstrokes were actually getting you 1.1–1.3m/s that you discover what happened!
Compared to other fins it feels like cheating.”
