When you're looking to go fast on the trail, look no further than the Nike Air Zoom Terra Kiger 5 Trail Running Shoe. It's built for speed with a comfortable and lightweight design, and now features an updated outsole for improved performance on wet and variable trail conditions. Previously known as a shoe that stuck to mostly dry trail surfaces, the Kiger 5 now features a sticky midfoot rubber compound for improved traction on slick roots and rocks. The front and rear of the outsole still feature high-abrasion rubber and a lugged design to dig into the trail, but you'll now have a more reliable center grip when dealing with slippery conditions. The shoe has also been updated with a full React foam midsole, which delivers a smooth and responsive ride on hard trail surfaces, as well as forefoot rock plate that offers protection from sharp rocks and other trail hazards. A snug lacing system gives you a comfortable and supportive fit for rocky and technical trail sections, while a special Zoom Air unit in the heel provides added cushioning to accommodate the heel strikes that you often see on long runs and variable terrain.
