The GEL-SONOMA 15-50 shoe is rooted in the concept of outdoor exploration. This style takes inspiration from the upper of the 15-50 running shoe, originally designed for competitive runners tackling a variety of terrains. It is now reworked for strolling through city streets and mountain trails. The structure utilizes components from the first two GEL-SONOMA trail shoes. From daily urban walking to hiking on rocky slopes, these features provide advanced cushioning and traction in various environments. The upper is inspired by the 15-50 running shoe, with layered heel reinforcement for improved durability against abrasions. It follows the same structure as the first two GEL-SONOMA trail running shoes and features GEL technology in the rearfoot for everyday comfort and an outsole grip that enhances grip on off-road surfaces. The upper also takes inspiration from the studded upper of the 15-50 cross-country model and borrows its construction from the first two GEL-SONOMA trail shoes for maximum comfort in everyday life.
