I took the advise of the other buyer and bought a size 8 when normally I would order a size 8-1/2.  The size 8 fits great with plenty of room for my winter socks and they look very nice with the top rolled up to make the boot look much nicer and warmer.  I have not tried them out yet, but I do believe they will be warm and waterproof while walking my dog next winter.  Great boot at a great sale price!
