I read reviews before purchasing and a lot of people suggested going down a half size. I'm a size 8.5 in Nike shoes so I ordered a size 8 in these light grey. I ordered these for a museum field trip since we would be doing a lot of walking. There is some indentation near the tip of the shoe after all the walking I did. They are very comfortable, lightweight and look great! Definitely going to purchase another pair of Adidas soon
