Hi, Ashlyn! I guess that depends on the work you’re doing. The soles are certainly durable (that 5,000-mile warranty is for real), but I’d say if you’re working with sharper tools or machinery, the uppers might wear a bit faster than boots made of a thicker, more robust material. That said, for a textile upper (i.e. not a solid, thick pleather or similar), they feel fairly substantial.
