They had a very unpleasant odor emanating from the insole material. I've tried all kinds of detergents and odor eliminators but to no avail. Kept them on a table by the window in a sunny room, hoping the sunlight would help. Not good. You really stunk in the room. Very disappointed. For 60€ there should have been better material. Would have sent them back but didn't wear them until after I bought them. BIG MISTAKE!
