ONE SIZE FITS MOST: This universal, high top sock (19 inches tall) fits women’s and men??s left or right feet and is available in a single or 2-pack option. Compatible with short or tall walking boots. UNIVERSAL FOR ALL WALKER BOOTS & BRACES: Designed for use with all orthopedic walking boots, including post op surgical shoes, foot cast boots, closed toe medical walking shoes, air cam walkers, and air cast walker boots. USE FOR: These socks are intended to help reduce skin irritation while wearing a foot brace or walking boot. However, its mild compression also makes it useful for diabetes, leg fatigue, foot, ankle and leg swelling, circulatory problems, edema, and neuropathy. MATERIAL STAYS DRY TO ELIMINATE ODOR: This closed-toe, stretch tube sock is made with a cotton, polyester, lycra, and spandex blend. The latex-free, 100% synthetic fibers allow for superior moisture absorption to keep your foot and leg dry, while the thick cushioned-knit provides optimal warmth and comfort. NON-CONSTRICTING FIT: The improved cross stretch knit material provides targeted compression and heat retention to improve circulation around your sore foot, ankle, and leg, which reduces swelling and encourages blood flow to speed up your healing process.
