Bought and well worn and loved. I paid to have the soles completely redone. But post pregnancy, my feet are too wide for them. I had used sticky pads in the heel to keep them from sliding which I removed. There is still some stickiness in the heels remaining. They are best for a long narrow foot, as opposed to a short wide one. Bundle 3 or more items for 15% off and flat rate shipping. COS sold them to me as a size 7 (EU 38). Definitely best fits a 7.5 but more narrow one. Possible an 8 if someone is in between.
