Puma Fast-Trac Nitro GTX

The Puma Fast-Trac Nitro GTX is a weather-ready trail runner built for days when the route (and the forecast) won’t cooperate. With a waterproof, breathable GORE-TEX membrane and a durable ripstop-style upper, it’s designed to keep your feet protected through wet singletrack, slushy paths, and messy connectors on pavement. Underfoot, a responsive NITRO foam setup delivers lively cushioning, while a supportive carrier layer helps the ride stay controlled on uneven ground. Add PUMAGRIP ATR traction, and you’ve got a confident do-it-all option for winter running and door-to-trail versatility.
