Truefin

Truefin is a revolutionary fin for scuba, snorkel, and spearfishing.   (www.truefin.com)

It has the comfort and easy kicking of a highly flexible fin, while also having the high thrust of the stiffest technical fin.
Fish can self adjust the stiffness of an active fin according to their needs. In a new approach to mimic nature, Truefin has developed a swim fin with modular spines which lock into the fin and limit the flexibility of the blade to an optimum ‘angle of attack’ at all kicking frequencies for unparalleled efficiency and power over spineless swim fins.
