I typically walk three miles a day.  Since the day I got them in the mail these boots have been my go to shoes for the cold and snow.  I have no blisters, great arch support and they look pretty cool too.  I gave them four stars because from the pics they look like they are fully lined with flannel.  They are not fully lined. Where they are lined, the flannel doesn't quite do the trick.  If you are not wearing something tucked in or long socks it will rub against your leg.  I typically wear a size 6.5-7 and chose to buy the 5UK thinking I would be wearing thick socks as it is winter, I wish I would have bought a size smaller.  Which has been posted previously but it is worth mentioning again.
