What Our Gearhead(R) Experts Are Saying:"I've put the ACG Zegama through long days on rocky, technical trails, and the ZoomX foam genuinely holds up - it stays soft and responsive even when my legs are cooked. The Vibram Megagrip outsole inspires real confidence on wet rock and loose dirt, and the roomier forefoot is a welcome touch on big-mileage days when feet start to swell."The trail stretches long, and the terrain turns technical fast, and the Nike ACG Zegama Trail Running Shoe is built to keep us pushing. From steep, rooted climbs to fast descents over loose rock, this shoe keeps us moving with the kind of underfoot protection that lets us stop thinking about our feet and start thinking about the line ahead. The wider forefoot gives toes room to spread naturally, adding stability and comfort when the footing gets unpredictable. Nike packed the Zegama's midsole with ZoomX foam - the same lightweight, high-rebound material found in their elite road racers - tuned here for the demands of rugged terrain. That means substantial cushioning without the dead weight, keeping legs fresher over long efforts in the mountains. Underfoot, a Vibram Megagrip rubber outsole delivers the kind of traction we trust on wet slabs, muddy switchbacks, and everything in between. The engineered mesh upper breathes well and wraps the foot securely, so the shoe stays planted and comfortable from the first climb to the final descent.
