Same Altra quality I've come to expect, just designed differently from their other trail shoe (Lone Peaks). The cushioning is lighter than the Lone Peaks with more neutral lugs; basically, these were designed for a more groomed trail. If you're looking for a trail shoe to handle the more technical trails (rocks & roots) then you should consider the Lone Peaks ( more cushion, better, deeper lugs, and a rock guard). Still, the Superiors are a great shoe. Either way, I love my Altras!
