A sock used in pilates includes a medial support about an arch portion of the sock, a side support member extending longitudinally along a lateral edge, a metacarpal support member, a reinforcement member extending from a heel portion to the metacarpal support member, and a plurality of raised bumps strategically located on a lower surface to provide tactile response to weight shift and pressure due to posture that can be used to correct or adjust posture during pilates exercises.
