The Gel-Sonoma 15-50 sneaker is rooted in the concept of outdoor exploration. This model is inspired by the upper material of the 15-50 cross-country spikes. Originally designed for competitive runners navigating diverse terrains, it has now been modified for maneuvering on city streets and mountain trails. Components from the first two Gel-Sonoma trail shoes were used in its construction. From everyday foot traffic to hiking on rocky slopes, these features provide advanced cushioning and traction in various environments.
