He-man cliff hucker? This is not your boot. But for a tiny sacrifice in strength, it provides huge gains in tourability. Remove the tongue before ascending for easy striding and then replace it for descending power. It’s light, stiff enough, and has a generous range of motion and an ingenious walk/ski mechanism integrated into the top buckle. The carbon-cuffed TLT5 has never met a trailhead it didn’t like.
