Sz 7 blue patent sandal w/ crystal embellishments

I have had more compliments on these shoes, than anything else in my wardrobe!! They are actually a little bit more of a turquoise than pic shows. They have fun plastic crystals they are very carefully sewn onto A metal piece on the thong. As much as I’ve worn these.. I’ve never lost one! Very cushiony and comfy.. unfortunately, my feet have outgrown them! They were designer shoes.. I can’t recall name and logo isn’t helping!
