Employing a unique design concept that offers flex, fit and support along with a multi-fit footbed system and a breathable, unlined, armored mesh upper, the Salewa Fire Vent Trail Shoe offers technical performance and lightweight comfort for day hikes, scrambling and approach hikes. A synthetic upper made from micromesh, armored mesh and Aramidic rubber offer great breathability and durability and the 360 degree Kevlar rand increases foot protection on rough trails. Salewa uses their Three Functions System, which consists of Fit, Flex and Support, to offer a more precise fit. Part of this system is built around the Salewa "Y" design, improving fit around the heel and ankle while increasing flexibility through the collar of the shoe without giving up support. The climbing lace-to-toe lacing system makes a more customized fit possible in the toe box and adjusts well to the natural asymmetry of the human foot. The Fire Vent also offers a unique footbed that allows individual adjustment of the fit through Salewa"s Multi-Fit foot bed system. The bottom layer can be easily removed from this two-part foot bed to increase the volume within the boot for wider feet or left intact for medium to lower volume feet. An EVA midsole and heel shock absorber dampen impacts on the downhill and the Vibram Tech Approach, sticky rubber outsole offer sure footing on rocky surfaces. Sold in pairs, the Salewa Fire Vent Trail Shoe is available in full and half sizes.
