They are not extra wide calf boots. Maybe wide but not extra wide unless you're 120lbs. I got these in my reg size and though I like them, they are tight in my calves. I feel like Id need compression socks or to lose 10lbs to be able to wear them comfortably. I had a thin pair of leggings on with them. Not sure they're even able to be worn with jeans or anything else. I doubt a liner could fit inside and they get even half way up my calves. Size chart is off. They are solid boots and seem well made just off in the size.
