Color: Black Heel Height: 7cm Strap: With strap I've only worn these shoes about 5 times. My sneaker size is 24cm, but these shoes fit me perfectly in size 23cm (Japanese size). I've attached silicone non-slip pads to the arches of the feet (adhesive type). They've been on for a while and won't come off. Please check the fourth photo for confirmation. No box. I will ship them in simple packaging.
