This is the natural callus therapy that comfortably removes layers of tough, dead skin in a single treatment to leave feet soft and smooth. The disposable booties are lined with a mixture of 18 natural moisturizers and exfoliants, including fruit-derived alpha hydroxy acids, that slough away dead skin cells and help speed circulation. Simply wear the booties for one hour, then rinse feet clean. Within about five days (thicker calluses may take up to 14 days), the balm penetrates the hard skin and begins peeling it away, revealing pedicure-soft feet. Contains one pair. Booties fit women’s shoe sizes 4-12, and men’s sizes 4-13. 6" H x 5" W x 1" D. (6 oz.)
