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, now reworked for strolling through city streets and mountain trails. The structure utilizes components from the first two GEL-SONOMA trail shoes, providing advanced cushioning and traction in various environments, from daily urban walking to hiking on rocky slopes. The upper is inspired by the 15-50 running shoe. The layered heel reinforcement design improves 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.
