These boots are more like wides then medium width. Nothing a nice, cushy full insole won't fix! Also, they are wide calf, for sure. I have a 19.5" calf and these zip up over leggings. They didn't at first but after 3 days of wear they now zip all the way up. Buckle adjustment doesn't really help. I only rated these a 4 star because after 5 full days of wearing them, the sole is starting to show wear. The fake leather is nice and doesn't look like vinyl. I wouldn't pay full price for these but go for it during a really good sale.
