The Challenger ATR is a trail-worthy version of the lightweight, speedy Clifton road shoe. For version 3, wear-testers reported that the toebox felt roomy. It’s one of the few tweaks Hoka made to this shoe, opting to leave much else as is, thankfully. The midsole and outsole are nearly identical to earlier versions, though the lugs in the middle of the forefoot have been spaced out to better shed mud. The upper is breathable yet more durable, thanks to 3D-printed overlays that help hold the foot steady on uneven terrain and fend off trailside sticks and debris.
