Constructed from durable Monprene® for strength and designed with an ultra-slim profile, the S-Tek fins' pre-angled 30º blade requires less flex to achieve the desirable angle of attack for efficient kicking. This makes the blade stiffer without increasing friction, thus reducing the risk of leg cramps and ankle fatigue while offering, at the same time, unparalleled maneuverability and a high-performance alternating stroke.

• Blade with a clean design and openings to reduce friction and improve pushing performance.

• The Hydra-Loop system with an increased and reinforced blade angle improves lateral stiffness for significantly superior alternating kick performance and creates a better thrust performance thanks to the hydrofoil profile.

• The removable stainless steel plate weight system allows you to choose between positive, neutral or negative buoyancy fins.

• The two-part design of the S-Tek fins, featuring a separate blade and foot pocket, makes them easy to transport.

• The shovel and the shoe are made separately and joined with the robust Socket-Lock Connecting System, which facilitates assembly and disassembly operations.

• The open heel shoe is supplied with a resistant elastic strap which makes micro adjustments possible to better adapt to different types of footwear.
