I bought an 8.5. They fit great. I sized around the same as normal based on comments and feedback. I’m on my feet off and on at work and was having swelling mid-day. I feel great in these. In fact, I hope they come in different colors, as I’ll be buying more.
I’m normally an 8.5 in Converse and a 9 in New Balance, 8.5 in Sperry and 8.5 in Ugg. I hope this helps.
