I've only worn these once, but the hope for arch support to address my pronating feet, has not been helped much at all. I wore them for about 2 hours and got horrible blisters under/to the outer side of my big toes...haven't been able to wear any other shoes since (2 days ago),...I'd try to return them but there were worn for 2 hours....not happy at all to have paid $90 for shoes I most likely can't wear again.
