My husband wanted tall boots and these were one of the few we could find.  They are very comfortable and light weight.  He wears a 9 1/2 and bought size 10.  They were a bit snug when he first put them on but by the end of the first day they fit perfectly. He says they are very warm and have good traction, but he hasn't yet had the chance to see how well they'll keep his feet dry.
