A shoe held in place by a strap around the ankle above the heel:[as modifier]:high-heeled slingback shoes...
Spiky slingbacks and stiletto shoes and boots with elongated pointed or chisel toed front uppers will be made for showing off in rather than walking far.
Become a member simply by filling out a profile, and strappy slingbacks, sexy stilettos, and melt-worthy boots are yours at about 30 percent off retail.
The problem with slingbacks is that your heel is not held in place as securely as with pumps, so it lands at a slightly different spot each time you put your foot down.
