I wear a 9 in tory burch, and a 39.5 in European shoes (Chloe, chanel, AGL). My left foot is always trouble for me with shoes , and the right shoe is always a little big but it's the only way they are comfy for me. I bought a 39.5 in these. I wear smart wool no show socks and the fit is perfect. Does anyone treat these before wearing?
