I would strongly recommend against buying used boots for hunting. If your feet are not comfortable, you will not be comfortable and an uncomfortable hunters is not paying attention to what is happening around him and he probably will not stay in the field as long as he would if he wasn't thinking about cold or uncomfortable feet. After you wear a pair of boots for a while they will conform to your feet, you do not want boots that have conformed to someone elses feet. It is your money so you are free to buy what you want, but hunting boots is one place I would not penny pinch.
