The GEL-SONOMA™ 8 GTX shoe is designed for the great outdoors. It's a durable trail model that's made to provide good grip on off-road surfaces. With a GORE-TEX upper construction, this shoe helps prevent rain and snow from entering the shoe’s interior. It's also functional for improving the shoe's fit and making it more breathable. Underfoot comfort stems from a full-length AMPLIFOAM™ PLUS midsole and GEL® technology unit that's strategically placed where cushioning is needed. Lastly, the trail-specific outsole is functional for providing advanced traction. Its pattern helps you experience a confident stride on the uphill and downhill sections of challenging terrain.
