Mares Fins X-One s

The perforations prevent stagnating water flow from slowing you down. Eliminating this “parachute effect” you’ll slide faster through the water. Furthermore the openings eliminate any suction effect, making doffing easier.

The Split Fin Improves thrust with reduced effort.

A sturdy, buckle-free design.

Soft longitudinal inserts allow a controlled deformation of the fin blade while kicking. This channel shape moves a greater amount of water resulting in more thrust for the same effort.
