These are back strap sandals from PELLICO. I purchased them from the major online shopping site, Gilt. I've worn them 2-3 times, and I'm selling them because I'm decluttering. Heel height is approximately 6cm. They are very light and easy to wear, with a simple design that won't get old, and they are easy to match with various outfits. I had the front and heel soles re-soled at Urawa Isetan. That alone cost 5000 yen. A storage bag is included. I like them, so I may suddenly delete the listing. Thank you for your understanding. Size 34, Japanese size 21cm. Although they are labeled as 21cm, I usually wear 22cm shoes, and these fit me perfectly. These are also my perfect size.
