DescriptionThe GEL-SONOMA 15-50 sneaker is rooted in the concept of outdoor exploration. This style harnesses inspiration from the 15-50 cross-country spike’s upper. It was originally designed for competitive runners racing on a wide range of terrain. Now it’s modified for maneuvering on city streets and mountain trails. Meanwhile the tooling uses components from the first two GEL-SONOMA trail shoes. From everyday foot traffic to hiking rocky hillsides these features create advanced cushioning and traction in various surroundings.
