Kurt Geiger Crystal Butterfly London Lane Sneakers

Adorable women's sneakers by Kurt Geiger. Shoes are in excellent condition, appear to only have been worn once. Size is 40.5, and according to kurt geiger, that equates to 10.5 US size, but NO. I wear 10.5 to 11 and I can barely get these on. they're closer to a small 10. have a little dirt on inner ankle area, looks like dust. Some grit in the sole tread. 027C
