Made of three-dimensional carbon fiber material, it provides stability to the midfoot part of the sole and enhances the anti-torsion effect of the foot. Based on the principles of biomechanics, special cushioning/elastic materials and midsole materials are overlapped and combined to achieve a wedge-shaped dual-density midsole structure that has both energy absorption and stable support effects. The injection piece made of high-strength TPU material is designed on the outside of the forefoot, which greatly improves the lateral stability required for intense badminton sports.
