Z-coil Z-Breeze Mary Jane Wms Sz US 10 Styish Comfort Sold Out at Zcoil. Fun open design on top. There is little to no wear anywhere on the shoe. The coils are enclosed in a stack heel. The sole of the left shoe does show a small divot but it is not a full hole. This is the only significant flaw on either shoe. shoes are leather with a thick rubber sole.
