Often called Clifton for the trail, the new Challenger 4 looks even more like a Clifton with it's cleaner, less busy look and more breathable upper. Like the Clifton 4, the Challenger ATR 4 is fast and light, offering a super smooth ride.
Where the Challenger ATR 4 diverges from the Clifton and takes the path less travelledis in it's multi-lugged outsole. Arranged closer together towards the heel for a smoother, more consistent ride, it's 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 what the running surface, the Challenger ATR 4 has improved upper durability in the areas you need it like the larger toe guard area.
