Size S ■ Manufactured and sold by: SOL INTERNATIONAL Co., Ltd. ■ Material 【Silicone (T-Form)】 ■ Product Features 【Extra Soft Type】 The extra soft type was created based on the voices of swimmers and coaches who have flexible joints and find the conventional soft type too heavy, or feel that the load is too much. Although it has the same shape as the soft type, the flexibility of the blade part is increased to release and reduce the load on the feet and ankles during use. ・The foot pocket part efficiently receives the power from the kicking motion and is structured to moderately release the reaction from the water. ・The flexibility of the blade part is increased to release and reduce the load on the feet and ankles during use. ・By giving the foot pocket part a certain degree of hardness against the flexible blade, it prevents the pocket from stretching or wobbling during the kicking motion. This structure firmly receives the force applied by the foot during kicking and transmits it as propulsion! 【HYDROTECH 2-Fin SWIM】 ・The fin blades, which have different shapes on the left and right, have a special shape that has been meticulously designed to prevent unnatural twisting of the ankles and legs. ・The most distinctive feature, the V-shaped V-Rail on the side edges, responds well to even harder kicks and generates powerful propulsion. The V-Rail has obtained world patents in Australia and the United States. ・The underside has a non-slip shape for safety. There are holes for water drainage on the underside of the toes, which prevents unnatural convection during kicking, provides a comfortable fit, and allows water to drain at high speed. ・The heel strap has no risk of blisters and fits firmly with moderate elasticity. ・Sold as a set of left and right. ■ Size S: 22.5～24.5cm (US: 6-7) * Please select your size based on your shoe size. ■ Color Variations TEALBLUE (TBLU): Teal Blue
