My feet and toes get very cold very quickly so being outdoors in the cold was often a struggle.  The day I recieved my boots in the mail we had a big snow storm.  I needed to shovel the sidewalk for the dog to go out so I just slipped on the boots... BAREFOOT... and thought I was going out for a quick shovel.  Well.... my feet were so warm I ended up doing the entire driveway (at 5am in my PJ's and Northface Coat!).  They are a bit bulky... but are still cute with jeans tucked in if you are trying to be somewhat fashionable.  I am convinced that Sorel is the only boot for me going forward.
