The design for shock absorption and optimized movement provides even support and cushioning from the heel to the toes, which helps reduce fatigue, enhance running performance, and prevent common running injuries such as shin splints. ?Detachable Heel Pad and Deeply Concave Heel Cup?: They encase and stabilize the heel, reducing the foot's movement within the shoe, thereby improving stability. This design more evenly distributes the impact forces on the heel, reducing pressure concentration, and minimizing vibrations to the heel and the entire foot structure. It alleviates heel pain that can arise from long periods of standing or walking. It is particularly suitable for foot conditions such as heel spurs and plantar fasciitis. ?Removable Metatarsal Pads?: Metatarsal pads play a crucial role in supporting and stabilizing the foot, which helps maintain balance and stability during walking, running, and standing. They provide the correct posture and anchor points for the foot, reducing unnecessary sway and torsion, and decreg the concentration of pressure in the metatarsal area, thus reducing pain and the potential risk of injury. (If you need to engage in vigorous sports, please remove the metatarsal pads.). ?3DDAPT Shell?: The 3DDAPT technology helps to redistribute pressure points on the plantar surface, reducing concentration of pressure in specific areas, thereby decreg the risk of pain and injury. It features enhanced elasticity, durability, and breathability. These structures are lightweight yet provide sufficient support, offering excellent shock absorption and energy return, which contributes to better comfort and functionality.
