I wanted a slip in shoe that would be warm enough to wear in the snow but high enough not to get my socks wet.  Well this is it.  There has been snow on the ground since November here in Michigan with minus degree temps and these shoe boots have been used almost daily.  My only complaint is that they are quite heavy but I think of it as a little weight training to shape up the legs.  I am not disappointed in this purchase and would recommend them to everyone.  Be sure to buy a half size up so you can wear thicker socks.
