Ergonomic hand swim fins designed to improve propulsion, technique, and training efficiency. Key benefits Better propulsion and speed: The fin shape channels water to increase forward thrust and help you swim faster with each stroke. Smoother, more efficient strokes: Ergonomically shaped according to natural mechanics to promote correct hand entry and a cleaner pull through the water. Secure, consistent training: Durable silicone bands hold the fins firmly in place so you get reliable feedback on technique without constant readjustment. Durable, performance-focused construction: Made from high-quality PC and silicone for long-lasting use and consistent performance under strict quality control. What makes this product stand out Ergonomic design developed on natural-mechanics principles to support proper hand orientation and motion in the water. High-end materials (PC + silicone) that resist wear and maintain shape and performance over repeated sessions. Built as a practical training aid for both learning and performance improvement — suitable for instruction and athlete conditioning. Function and compatibility Function: Increases stroke effectiveness and helps isolate and train hand positioning, pull strength, and timing. Compatibility: Designed for adult hands; intended for use in pool training, swim lessons, and athlete workouts. Attachment: Durable silicone bands provide a firm, easy-to-use fastening method to keep the paddle aligned with the hand during drills. Typical use scenarios Swim lessons and beginner training: Use the fins to give learners tactile feedback on hand placement and to build confidence while developing basic stroke mechanics. Lap training and technique drills: Add the fins during focused sets to reinforce a smooth catch and stronger pull, helping swimmers maintain proper form at speed. Athlete conditioning and power sessions: Competitive swimmers or triathletes can use the fins to increase resistance and improve upper-body propulsion during targeted workouts. What you get A pair of ergonomic hand fins made from PC and silicone with durable silicone bands for secure attachment — a simple, practical tool to support technique development and speed training for adult swimmers.
