These are the Knit Opera Shoes, a collaboration with Cotrip, from the brand Crolla Barriere, which I purchased last month. I own other Cotrip collaboration items, and they have cushioning in the heels, so my feet don't get tired even when traveling. The color is navy. They are new and unused, and this size is already sold out. Thank you for looking. Size: 23.5cm Color: Navy
