- Increase your techniques and speed: these short fins are a professional training tool, recommended by trainers. They comfortably boost swimming speed and skill, making them ideal for snorkelling and various water sports. - Multifunctional design for stable propulsion: with an enlarged blocking surface and wide PU surfaces, these fins provide stable propulsion and strong power. They improve your kicking efficiency and help maintain an optimal swimming frequency. - Soft, slip-resistant edge: made of high density silicone, these fins offer a soft, comfortable fit and enhanced slip resistance, helping you feel confident during water activities. - Long-lasting performance and fit: designed for adults as short flippers with a front row design and soft natural silicone for comfort without constriction. The integrated protective layer and foot-adapted design add durability and deliver overall shock resistance. - Practical use scenarios: use them for snorkelling in open water to extend propulsion and reduce fatigue; for pool training and lap drills to improve kick strength and stamina; or for water sports practice such as surfing, kiteboarding, and other activities that benefit from stronger, controlled kicking. - Key attributes at a glance: function (training, propulsion, speed enhancement), compatibility (adult short flippers, front row design), size (adult fit), material (high density silicone, PU surfaces), performance (durable, shockproof, slip-resistant).
