I purchased these for use in a hospital administrative position, but I never wore them because the company provided me with nurse sandals. They are new and unused. The insole is cushioned, making them less tiring to wear. They have a cute cross design. - Color: Black - Size: S (21.5-22.5cm) - Sole design: Non-slip The back strap is adjustable, so they should fit even those under 22cm.
