I wanted a rain boot that is comfortable, sturdy, cute and/or classy, and VERY IMPORTANT, Made in the USA.  My Sloggers meet every one of those criteria.  I ordered a size up, following the recommendation of several reviewers, and it fits perfectly with a heavy sock.  I have even worn them all day in the house just to avoid the task of changing shoes every time I went outside.  They are warm and comfortable.  The most amazing thing, though, was that these boots seem to shed water and mud before it tracks into the house!  The first time I wore them in the snow, I looked back across the floor to see where to mop up my wet tracks and there were none!  I will never buy another brand--but then, I don't expect to ever need another pair of boots.  These are awesome!
