Ive always loved any Stiletto's with a ankle strap.But I have really loved the locking ones.The idea of being locked into a particular "cruel shoe"while being made to do or serve.
Yummmmmmmmm The problem is cost those locking models can be cost prohibitive.Pleaser shoes has made those dreams a little more obtainable.They Have a line of Ankle cuffs styled around there line of shoes.A reasonable price $8-12 for locking and buckled styles.If your equipped with some leather tools a few rivets and some contact cement.You could attach these to your targeted Stiletto Slave Shoes.You could also just attach some chain to a "O ring"that slips over the heel spike and there fore making them usable on any shoe.
Even if You decided not to alter your shoes these are some very low priced ankle cuffs.
