I have a large size 12.5 foot and the 12 is fitting with room to spare. The toes in this boot feel loose and most of the "grip" is coming from the top of my foot. They are comfortable to wear but I could potentially see a problem with the boot getting stuck in the mud and my foot not staying with it. Color and look is right on as listed. Lots of room in the calf to shove pants into. I do wish Bogs offered half sizes, I might go 1/2 smaller
