Speedo Switchblade Fin

The 10-degree angle is designed to mimic the natural position of your foot during a flutter kick. By aligning the blade with your natural range of motion, it helps you maintain a more efficient, powerful kick cycle without forcing your ankles into an unnatural position.

The Switchblade features specific midfoot flex points designed to reduce the strain that often leads to cramping. By allowing the fin to flex more naturally with your foot, it minimizes the resistance that typically fatigues the arch during extended use.

The side rails act as stabilizers that help guide your kick. They encourage proper hip rotation and ensure that the energy from your downkick is transferred directly into propulsion rather than wasted movement.

These are versatile enough for any swimmer looking to improve their technique. While they are engineered to refine stroke mechanics for competitive training, the comfortable, extended foot pocket makes them accessible for anyone wanting to build endurance and improve their kick efficiency.

Unlike standard fins that often rely on simple resistance, the Switchblade uses a more technical design with specific flex zones and an angled blade. This focus on biomechanics helps you train your body to move more efficiently in the water rather than just adding weight to your feet.
