Unused black yoga socks, size M, excellent fit and design. - Size: M - Color: Black - Condition: Unused Thank you for viewing. Are you interested in trying these out before committing to more expensive options like Runway Cure Sole or Core Supporter? These have only been tried on. These are imported products. If you would like two pairs, how about 2880 yen? These socks also give me the feeling of improved posture.
