Do not purchase. I did not purchase these from Backcountry and this review is not a reflection of Backcountry but of the Mudstone boot and Garneau in general. I do not want anyone to think these are a good boot. The mudstone winter boots stitching comes undone after 2 months if use and they are unwilling to work with you even in the dead if winter when your toes freeze. Garneau offered a warranty replacement (which was appreciated) however they required you to send them back first with a 2-3 week turnaround. Garneau would not even send a new pair first after offering to purchase the new boots with refund upon return of the defective pair and would not allow one to return the boots after the weather warmed up.
Familiarity: I've used it once or twice and have initial impressions
Size Bought: 43
Both zippers broke on the very first attempt at trying them on. They're are very difficult to get on and off. The fit is ok once they're on. However, if you had thick socks on these would be damn near impossible to get on and off.
