The Brooks Catamount 4 and the Brooks Caldera 8 share the top of Brooks’ trail lineup, with two complementary missions: speed for the former, very long distance for the latter.
The Catamount 4 is much lighter, nearly 40 g / 1.4 oz less on the scale. The Caldera 8 answers with volume: its taller stack makes it the more protective of the two, while the Catamount stays closer to the ground.
Their midsoles tell two different stories. The Catamount 4 combines nitrogen-infused DNA FLASH v2 foam with the Pebax SkyVault plate: the propulsion feel is very pleasant and the ride stays controlled and stable, with a rather firm character.
The Caldera 8 relies on a thick layer of DNA LOFT v3 with a balanced feel that leans firm, and it makes you feel like you are running lighter than its weight suggests.
On grip, both share the TrailTack Green rubber, very grippy on dry and wet ground alike. The Catamount’s lugs, 3.5 mm deep, and the Caldera’s 4 mm lugs stay reasonable: perfect on runnable, hard-packed terrain, they reach their limits in deep mud.
Intended use decides the rest. The Catamount 4 is the shoe for races and fast outings, from short to intermediate distances, with improved protection on this version. The Caldera 8 is built for ultras: nonstop comfort, stability from its wide base, and a geometry that strings transitions together effortlessly, made to last for hours.
Budget follows the specialization: the Catamount 4 is the pricier of the two, about $20 more.
Catamount 4 or Caldera 8: which should you choose?
If your runs lean toward ultras, beyond 50K, and comfort comes first, the Caldera 8 is the better choice: sturdy and protective, with generous cushioning built to last.
The Catamount 4 is for trail runners chasing performance: races, fast workouts and runnable terrain, where its low weight and its plate make the difference. Its firmness, though, can wear on you over very long runs.
