The GEL-SONOMA 15-50 sneaker is rooted in the concept of outdoor exploration. This style is inspired by the 15-50 cross country cleat upper. It was originally designed for competitive runners who run on a wide range of terrain. Now it's modified to maneuver city streets and mountain trails. Meanwhile, the tooling uses components from the first two GEL-SONOMA trail shoes. From everyday foot traffic to hiking on rocky slopes, these features create advanced cushioning and traction in a variety of environments.
