The GEL-SONOMA 15-50 sneaker by Asics is rooted in the concept of outdoor exploration. Inspired by the upper of the 15-50 long-distance running shoe, originally designed for competitive runners on varied terrains, it has been reworked for city streets and mountain trails. The structure incorporates components from the first two GEL-SONOMA trail shoes, providing advanced cushioning and traction for urban walks and rocky hikes.
