Saga University x Craftsmen Joint Development! Tabi-style Running Socks (Right Foot Only) These high-performance running socks were born from a joint research project between professors and students at Saga University. Like tabi, the big toe is independent, enhancing gripping power and stabilizing form. Materials are used differently for each part of the sock, combining sweat-wicking polyester and supportive nylon in a design that is comfortable and less prone to stuffiness even over long distances. This is a listing for the right foot only. Recommended for spares, those who have lost one sock, or for experiments and research. Lightly washed and in good condition. How about these rare Saga University joint development model socks?
