These are TOMS heel sandals. I purchased them at a pop-up store for sample products that TOMS held at the Gotemba Outlet. I bought them, but I haven't had a chance to wear them, and they've been sitting here ever since. Since they are sample products, there is no official information, but I definitely bought them at a TOMS store, so they are authentic. Please understand that some time has passed since the purchase and that they are sample products, and please check the photos carefully. Thank you.
