I'll shoe pain with you, my body has discovered it can make delayed pressure urticaria (hives) especially on my feet and lower legs. They know exactly where my outside shoes, mostly slipper flats, touch them. Wore my nearly flat shoe boots and ended up with a neuroma in the arc of a foot.
On the doll shoe end the Converse store had keychain shoes with Union Jacks that would fit my Obitsu 60 and Dollzone minis. They only come in right shoes and not human size. Otherwise I would have scooped up several pairs and sold a few here. The DZ 70 twins have a pair of creepers I'd like to match but not for as much as I paid for them :/ *By which I mean the dolls themselves.
