I?d say I have medium-wide feet. He not only purchased them, but put my shoes on them as well. I lost a few pounds off my waist and got compliments on weight loss before I noticed for myself. Enough to say, that deserves 5 stars. Very easy to install and seem sturdy. This pair was a mistake for sure. Shoes fit very good and she enjoys the feel and ease of putting them on. Fit and worked perfectly! Unless sweaty pits dont bother you and the smell is all you care about. I usually love Birkenstocks though, so hopefully I find a pair sized correctly.
