Achieve your speed goals in the men's GEL-SONOMA™ 4 performance trail running shoe by ASICS. With lightweight cushioning to help you move faster, this trail running shoe provides all the support and protection you need to take on even the toughest of outdoor routes. The midsole of the shoe is made from soft, light AMPLIFOAM™ material that's been specially designed to increase flexibility for runners who want to concentrate on their speed. This is complemented by GEL® technology in the rearfoot area, which absorbs shock as your feet hit the ground and adds extra bounce to your stride. We know stability is crucial when you're tackling a trail run, so this shoe features an internal heel counter to help you move in your natural line of motion as well as a no-sew medial reinforcement for added support. As a stability shoe, the GEL-SONOMA™ 4 model is recommended for runners whose feet tend to roll inwards - this is sometimes known as overpronation. We've packed all this technology into a sleek and streamlined shoe that's versatile enough to tackle any outdoor terrain. Try the GEL-SONOMA™ 4 shoe, and you'll soon be on your way to your fastest trail run yet.
