I usually wear women's 7.5. I ordered them in mens 6 and they are perfect. I have arthritis in my toes and need a wider toe box. It's a good width in the fingers but not too wide in anything else. Personally I wouldn't use them for running or intense workouts as they flex too much for me (the stiff sole is best for my arthritis) but they are comfortable enough for running errands, walking the dog or a normal day. I can easily take out the insoles to put them on myself. The laces are horribly long so I ordered some no tie laces to replace them.
