Often called Clifton for the trail, Challenger ATR 4 looks even more like a Clifton with its cleaner, less-busy appearance and more breathable upper. And, like the Clifton 4, Challenger ATR 4 is fast and light, offering a smooth, smooth ride. Where it diverges and takes the path less traveled is in its multi-lugged outsole. Arranged closer together towards the heel for a smoother, more consistent ride, its lugs have a wider spread in the forefoot to help with grip on the trail and in wet conditions. Still as versatile and supportive no matter the running surface, Challenger ATR 4 has improved upper durability in the areas you need it (like a larger toe guard area). Let’s take to the trails, people!

Reinforced toe guard for an extra level of protection on rugged terrain
