I’m usually a 7 1/2 in other shoes. I got a 7 in this shoe and it fits perfectly. I love these shoes. I’m very active. I wear them when walking around town but I also wear them working out. I haven’t run in them, but I do lots of weight training. They probably aren’t the best for squats and things because of the cloud foam, but they’re so comfy that I just find myself putting them on everyday. I got the white ones. I can see how they might get a little dirty. If anyone has any info on how to wash these I’d love to hear it.
