These are practically brand-new, only worn once! I realized they didn't fit my foot quite right (I have weird feet, though!) too late to return them.

Pair it with a flowy dress, jeans, or a jumpsuit. --- Flat 1cm/0.34" heel Natural Armisia Argy herbal insole, with heel rebound, arch and forefoot support Heel Patch for added comfort Anti-slip rubber oustole
