Worn about 3 times. High socks with graduated compression design. These high socks feature a taping structure that supports the three arches of the foot and a graduated compression design for the calf. They support the inner longitudinal arch, outer longitudinal arch, and transverse arch of the foot, reducing the collapse of the arches, which can easily cause foot-related problems. By supporting the arches, they not only absorb the impact on the legs during landing but also allow the foot arches to act as springs, providing propulsion. The toe and heel areas inside the socks have a highly cushioned pile structure. The toes are reinforced with a high-strength yarn. In addition to the arch-supporting structure, they incorporate a graduated compression design that is classified as a "medical elastic stocking" under general medical devices. The compression promotes blood circulation, reducing swelling and leading to better physical condition. The base yarn uses recycled materials. Patent registered (Patent No.: 5704860)
