Pros Very light, looks great, burrito wrap tongue is far more comfortableVery protective midsole and upper, sock-like fit, grippy traction, lighter than previous versionPrecise fit, very grippy on rock, comfortable upper effectively keeps out debrisComfortable, low to the ground stability, lightweight, drains water wellSolid foot protection, good traction, drains water very well, heel collar keeps out debris
Cons Minimal foot protection, foam breaks down quickly, very long lacesExpensive, durability concernsNarrower than average, a bit pricey, not the lightestTraction not the best on slick surfaces, light on underfoot protectionA tad heavy, not super sensitive, narrow forefoot
Bottom Line A vast improvement over previous versions of this shoeThe highest performing trail running shoe that also comes with the highest price tagA precise fitting shoe that translates well into high performance, as long as your feet aren’t too wideOur favorite lightweight trail runner is capable of tackling any terrainA comfortable and supremely protective shoe
