Pikolinos leather sandals size 40. Size converts to 9.5 -10 in US shoe sizes. I feel these run a bit small. Adjustable Velcro straps and laser cut t-strap. I love that the back of these sandals gently curve around your heel.❤️. Can dress up or down. Have been gently worn twice and a little bit of wear on front, bottom sole. Heel is approximately 2.5”.
