I am a true woman’s size 7 and I took a UK five in these as they do run a little bit big which is a US 6 1/2 and they are perfect! I tried a bunch of sizes and colors and this is really what I recommend, going down a half size. Absolutely nothing wrong with them. I just got a couple pairs when traveling in Europe this summer and these are my least worn so I want them to go to somebody who will wear them all the time! 100% authentic not purchased from DH gate or a reseller, purchased from adidas.
