1. Shoes for men;end. Material: urethane, synthetic rubber;I. Height specification: 10 ~ 30mm [Used in accordance with the specification of the oral (last);2. The shape of the bottom of the foot of a normal person is different, but the back part of the sole is rounded and the side of the foot has a groove. When the person is standing or walking, the muscles of the round part are filled with the groove . Therefore, when the weight of a person wearing a shoe using a flat shoe heel having a height of 10 mm or more is 60 kg or more, the shock or pressure applied to the sole when walking or jumping is extremely large, but it can not be absorbed or prevented. And the front window (4.5m) of the shoe can not absorb the impact of the foot. Therefore, the present invention has been made to carry out the research which can prevent and absorb the impact or pressure on the sole. Shock resistant groove 20mm from the back.;I. A semi-circular shock-resistant groove with a width of 30 mm and a depth of 2 mm.;All. 50mm in the back, half in the width and 1mm in the depth, the grooved shoe heel of the new design with the anti-compression of the groin was made.;3. Effect;end. Shock absorption and compression prevention to improve foot comfort to reduce fatigue.;I. Flat shoe heel can not prevent slipping, but it prevents slipping and improves stability.;All. Resources can be saved in terms of material savings.
