Tri-Fin (Set of Left and Right) 【Swimming Training Equipment】 (For Competitive Swimming) Green (24-26cm) * Foot Size Guide The length of the foot can be adjusted with the attached rubber part. Basically, you can choose based on the size of the shoes you usually wear, but as the shape suggests, the width of the toes is important. If you have wide feet, it is recommended to consider a larger size as well. ◆ The material of the Tri-Fin body has also been improved and changed to the latest resin material. Optimal hardness and flexibility have been achieved. ◆ By providing drain holes at the toes, the water resistance in the foot pocket, which was a resistance until now, has been drastically reduced! ◆ New generation training fins that support all four swimming strokes: freestyle, breaststroke, backstroke, and butterfly.
