The Notre x Salomon Xt-4 “Grass Stained” is a collaboration by the Chicago-based retailer on a colorway of the trail running shoe inspired by the worn-in aesthetic of grass-stained shoes. Comfortable and full of character, a grass-stained sneaker serves as the inspiration for Notre and Salomon’s Xt-4 collaboration. The shoe features gradient green accents on a breathable textile upper with supportive seamless overlays.
