Puma Fast-Trac Nitro 4 Men's Trail Running Shoes
When the trail gets technical, the Fast-Trac 4 gets to work. This nimble, moderate-stack trail runner is designed for speed and control on steep climbs, loose descents, and rugged terrain. Now more durable than ever, it features an advanced Nitrofoam compound for high-rebound cushioning without the weight.
Engineered Mesh Upper
The upper of the Fast-Trac Nitro 4 has been created from an engineered mesh to provide a durable and protective shoe, while being extremely comfortable. The mesh allows cool air to circulate while at the same time removing unwanted warm air, helping to create a perfect microclimate where feet can thrive. The mesh is durable in high-wear areas, ensuring your feet are secure and always protected on the trail. Increasing support and durability, the upper includes PWRTPE on the lateral side to provide stability on difficult and rocky terrain. The soft, padded heel collar sits close to the ankle to increase comfort, while the minimal tongue prevents irritation caused by rubbing. The protective toe cap shields the toes from rocks and uneven surfaces, and the mudguard skin helps to repel mud, keeping you light and nimble on your feet. Completing the upper is a traditional lacing system which locks the midfoot to prevent excessive movement for a secure and stable fit.
Nitrofoam Midsole
The midsole of the Fast-Trac Nitro 4 features Puma's Nitrofoam, a nitrogen-infused material designed to be lightweight and responsive. This technology provides high energy return and maximum propulsion, allowing for increased speed and endurance. By expanding the midsole through nitrogen infusion, the shoe offers significant underfoot comfort and absorbs impact forces on hard surfaces. This design helps reduce joint stress and the risk of injury while assisting the wearer in achieving peak performance.
PUMAGRIP ATR Outsole
The Fast-Trac Nitro 4 features a PUMAGRIP ATR outsole designed to ensure exceptional grip across various trail surfaces. This durable outsole provides reliable traction even in adverse conditions, such as icy or technical terrain, to support you on challenging routes. Completing the outsole are multi-directional lugs which dig into the ground for biting traction.
