I usually wear a 6.5-7 shoe and I ordered the 37. It felt big when I first put it on as there was a lot of room between my toe and the end of the shoe. But since I'm on my feet for long periods of time, the extra room is quite welcome and doesn't hamper me in any way. I work at a department store so I'm constantly walking back and forth, and I hardly think about my feet anymore. The shoe was a little stiff at first, but it's canvas and doesn't require a long breaking in period. The arch support is pretty good. I have low arches and I get good support. I also have narrow feet so the laces come in handy.

**Update** It's been 9 months since I purchased the shoe and it's showing a little wear. I will definitely purchase again. On occasion I've been allowed to wear my regular tennis shoes to work, and I have to say that my Danskos were far more comfortable. My feet and legs get tired, but they don't hurt. Looking forward to getting a new pair!
