The Speedo Biofuse Swim Training Fins are short blade fins designed to help swimmers focus on perfecting stroke technique, while strengthening leg muscles and overall endurance. By increasing resistance without reducing tempo, Biofuse fins allow you to build power in your kick. Upper leg muscles - the primary focus of fin training - account for a very large portion of the body's musculature.
New for 2017, Switchblade Fins by Speedo were designed for premier performance and unmatched comfort. They're the ideal fin for professional athletes, surfers, and fitness swimmers. As Speedo product manager, Grace Anne Sanderson puts it, Switchblades are "the fin that everyone has been asking for." Designers in the Speedo lab tested numerous blade designs, seeking the blade shape with the greatest balance.
Speedo's Short Blade Training Fins offer increased resistance without hindering your natural kicking tempo, making them the ultimate training aid for improving flutter kick speed, technique, strength and endurance. Speedo designed the Short Blade Training fin's stiff silicone blade with a slightly larger surface area than the foot, allowing for more resistance and a greater propulsive force. The short, short blade shape promotes short, fast kicks.
Made from durable injection-molded EVA foam, Speedo's Nemesis Training Fins prepare you for a winning season (and make you look totally bad-ass). The Nemesis' design mimicks the fin of the humpback whale: the curvature, outer ridges, and sweeping channels funnel water with every up- and down-kick, providing the user with powerful propulsion. Plus, the gentle curve makes this fin acceptable for breaststroke practice, in addition to fly, free, and back.
