Laurie G wrote a review of The North Face McMurdo II Boot - Women's on April 23, 2013
Well, I put these boots to the test. They kept my feet dry and warm. I hiked, snowshoe, shoveled, and walked in several inches of show in temperatures of sub-zero to mid 20's I would recommend these boots. But if you are one who does not move around in the winter and are looking for a boot to keep your feet warm.. put a foot warmer in your boot. You can buy instant foot warmers. They are like the instant hand warmers, but designed for boots. Most boots are designed with activity in mind, not for standing around. Your feet will get cold in any boot if this is the case. These boots do run very small. I wear a 6 boot with room for additional sock. Not so with theses boots. I had to go to a size 7 and can not put another sock with them. The boots are also light weight which is something a 4'11' , 94 pounder adult looks for. Over all I would still recommend these boots knowing these facts.
