Borrowing the design of its upper from the 15-50 cross-country spike, Asics' Gel-Sonoma 15-50 is a rugged shoe that looks the part in this Coffee Desert Camp colorway. The upper combines an Earthy tie-died mesh with dark brown hairy suede and leather overlays. Underneath, a Gel-cushioned midsole offers impact absorption and comfort, a Trusstic System sole helps maintain the shoe's structure, and the black rubber outsole offers deep ridges for traction across a variety of surfaces.
