Windchime, I agree 100% with what Elizabeth P. says. They do not fit the way regular Cons fit (which is the whole reason I can wear them; I can't wear regular Cons at all -- too flat, too wide, etc.)
These are narrower and a bit shorter. I usually wear a 6.5 in North American sizes or a 37 EU size. In these, I wore a 7 and needed it.
I find them INCREDIBLY comfy. I sort of bounce around in them like Tigger, actually. They are too hot for the hottest days, but they're fabulous in the late spring/ early fall weather and on cooler summer days or evenings here. They're also a fantastic rainy day choice with an umbrella if you are just kicking around town and don't want to spoil your sandals.
