This is a great boot! Best of all, made in the USA! Just got them today!  The pair I got ran a full size small. I don't know if it was because they are insulated but I could hardly get my foot in them. This is the first pair of Chippewa boots I have ever bought. I own Red Wings, Timberland and Wolverine boots and they all are the same size as what I ordered in Chippewa. But I will have to send mine back for a refund. I really hate that too because I really needed them and for some reason, the price for a size larger is almost $50.00 more! I don't understand that but I won't be ordering another pair.
