I work outside in wet/muddy environments and on boats. My boots are frequently being saturated and dried. This product seems to hold up to everything I throw at it. I used to purchase cheap boots on sale from Sports Authority and similar department stores until I found these at a RackRoom Shoe store. The first pair lasted a full year, I've been purchasing these from Amazon ever since (RackRoom stopped carrying them). This is the first pair of boots that I wore the soles out before the rest of the material.<br /><br />These boots are comfortable, but need inserts if you have arched feet like mine. Otherwise, they can become uncomfortable after a days use.
