- Integrated water‑flow channel: a built‑in diversion port directs water efficiently along the blade, allowing faster drainage and reducing drag for smoother, more efficient kicks. - Full‑foot ergonomic fit: a comfortable, anatomically shaped foot pocket that sits snugly around the entire foot for secure wear—designed to stay in place during active swimming. - Soft, durable silicone construction: made from flexible silicone materials that are lightweight yet resilient. The soft feel reduces irritation while providing long‑lasting stability and flexibility. - Wide blade for strong propulsion: the broad fin surface produces powerful thrust, helps maintain an efficient kick cadence, and delivers stable forward drive with each stroke. - Low resistance and improved efficiency: the combination of water‑guiding channel, flexible silicone, and wide blade reduces effort per kick so you swim farther or train longer with less fatigue. Key attributes - Function: directs water flow, speeds drainage, lowers resistance, and increases propulsion. - Material: soft, flexible silicone for comfort and durability. - Fit: full‑foot pocket for secure, ergonomic wear. - Performance: wide blade for strong, steady thrust and improved kick frequency. Typical uses 1) Swim training and technique work: helps swimmers focus on ankle flexibility and kicking power while reducing drag; ideal for lap work and interval training. 2) Snorkeling and surface recreation: provides controlled, efficient propulsion for relaxed snorkeling and surface swimming in lakes, bays, or calm seas. 3) Water fitness and rehabilitation: low‑resistance design and comfortable silicone fit make the fin suitable for aquatic exercise, rehab sessions, and therapeutic mobility work. Care tips - Rinse with fresh water after use and air dry away from direct sunlight. - Store flat or hanging to preserve blade shape. This fin combines directed water flow, an ergonomic full‑foot fit, silicone comfort, and a wide blade to deliver reliable performance for training, snorkeling, and aquatic fitness.
