They fit great. The Last is very generous. I’m using the inserts and my Dickies socks (about the thickness of a Darn Tough Lightweight cushion). With my thin socks they are a little sloppy. I think if I didn’t run the inserts AND wore my thin socks, I could have sized down 1/2 from Brannock. However with the side welt, I can feel it touching my ankle with thin socks, so I prefer to wear these with a slightly more substantial sock. I also think during the winter I can remove the insert and wear my super thick socks. I might try it this summer just to validate. I don’t regret this sizing though. It’s very comfortable and no heel slip. I saw many suggested TTS and I don’t feel it’s wrong. It might just be this Munson Last is more generous than their other Lasts.
