The true one-size-fits-all disposable slipper. Supply each client with their own pair when they come in and let them take them home when they leave. Skid resistant sole provides protection when walking on wet, slippery or hot surfaces. Spa Flappers adjust from men's size 12 to women's size 6 by simply tearing the perforations at the heel and toe to fit the foot size of the individual. Black. 1 pair.
