I have the Active Winter Rider boots and love them. I got them in a 7R and they're perfect for my 14.5" calves. I have rather narrow feet so I have some extra room in the foot bed but I think that works out perfectly considering I like to be able to wiggle my toes around in my boots especially in the winter. They are warm enough to not need super thick socks or anything like that and I found that they broke in quickly without a lot of stiffness issues. The profile is also not so bulky that you'd need to worry about fitting in your regular stirrup irons, etc. if you're seriously riding in cold weather, i'd recommend these.
