FAAS 500 TR v2 GTX® Trail Running Shoes:The FAAS 500 TR v2 GTX® Unisex is a trail running shoe built for the rigors of the toughest of terrains with an impermeable, waterproof upper for wet weather conditions. At a 4mm heel-to-toe drop the shoe encourages a more midfoot strike particularly relevant for trail running. This version has been upgraded with WeaveMesh technology in the upper to provide lightweight midfoot support.
