These socks bring relief to dry, rough, calloused feet. To use, apply your favorite foot lotion, then slip on the socks. Designed with our special THERMA-FLO weave, these unique therapeutic socks work with the skin to help absorb and retain the valuable active oils that keep feet looking and feeling soft and smooth. Keep the sock on overnight after applying lotion. For best results, use with Earth Therapeutics Tea Tree Oil Foot Repair Balm.
