⭐︎Grant E One's⭐︎ I opened the package of a set of 3 pairs, but they are new and unused! Energetic socks, perfect for both business and casual styles, are now available in an ankle-length design! The far-infrared effect of KODENSHI® keeps your feet warm. The entire sock is treated with Hyper Ion processing, eliminating foot odor!
