Ordered half size up as several reviewers advised. Calf is still snug with skinny jeans, but not so much that zipper is straining. Extra room in the foot lends itself to some aches in leg and back after a long day on my feet, so I need to look in to adding some extra cushioning and support. The shape of the toe is strange - odd mix of pointy and rounded. Warm and well made - these are adequate and no frills for a moderate price.
