The reason I mentioned it was because shoes today are not sewn to the bottom anymore, they are glued. I was reading of a guy in a sub tropical climate with a pair of hiking boots on that the soles came off due to heat. If the glue gave due to eat then how would material react with altitude. It was just a thought.They are for sure not a winter boot, as they are breathable nylon. These are mainly for urban tactical operations, however U.A does make a winter boot. Altitude, I'm not really sure, besides temp, what effect altitude has.
