S-Tek Fin is a purpose-built, next-gen technical diving fin providing maximum power when you need it.
Constructed of durable Monprene® for maximum durability and designed with an ultra-streamlined profile, the S-Tek Fin’s 30º pre-angled blade requires less deflection to achieve the desired angle of attack for an efficient kick. This allows for a stiffer blade without increasing drag, thereby reducing leg cramps and ankle strain while delivering unbeatable maneuverability and alternate kick performance.
