Some owners claim you will want to sleep next to them? Their honest full-leather design and hardy Vibram sole can be worn for years, and just when you think they are on their last thread they can be rebuilt. This is not too much to ask from the quality companion of your feet; a true handmade sole mate! The 10″ full-grain leather upper with double sole construction is available with optional hard celastic toe or ANSI approved steel toe. The Smoke Jumper meets or exceeds the requirements in accordance with the NFPA 1977, Standard on Protective Clothing and Equipment for Wildland Fire Fighting.
