The Brooks Catamount 4 is the kind of trail shoe that feels like it’s ready for adventure the moment you lace it up. Unlike the bulkier, ultra-cushioned options in the Brooks lineup, the Catamount is designed to be light, fast, and agile—perfect for those days when you want to push the pace on trails without sacrificing protection. What stood out to me right away was how connected it felt to the ground while still offering plenty of cushion underfoot. It has that sweet spot balance of speed and security, making it a fantastic choice for trail races or faster training efforts where efficiency really matters.

Upper
The upper of the Catamount 4 feels sleek and race-ready. The engineered mesh is lightweight and breathable, keeping my feet cool even during longer efforts, while the overlays and gusseted tongue helped lock down the fit. The heel collar is lightly padded, giving just enough comfort without weighing things down. The fit overall leaned toward snug and secure, which I appreciated on technical descents when I didn’t want my foot sliding around. The toe box isn’t overly wide, but it’s not cramped either—it felt performance-oriented, which worked well for me on faster runs.
Midsole
The DNA FLASH v2 midsole is what really gives the Catamount 4 its character. It’s nitrogen-infused, which means it feels both light and energetic. At 32 mm in the heel and 26 mm in the forefoot, there’s enough cushioning for longer distances, but it’s not a “sink-in” kind of softness—it’s firmer and more responsive, which kept me moving quickly on rolling terrain. The SkyVault propulsion plate adds a snappy toe-off that I could feel especially when climbing or surging. For me, it felt like the perfect mix of protection and speed, making it ideal for trail races or harder training days.
Outsole
The outsole uses TrailTack Green rubber with 4 mm lugs, and it struck a nice balance between grip and versatility. On dry dirt, loose gravel, and rocky trails, I felt totally secure, and even in light mud it held its own. It’s not as aggressively lugged as some deep-mud shoes, but for most trail conditions, it worked really well. What I liked most was how smooth it felt on sections of road or hard-packed trail—no clunkiness, just a clean transition. Durability also looked strong after multiple runs, with the rubber barely showing wear.
Performance on the Trail
Out on the trail, the Catamount 4 felt fast, agile, and fun. It’s not the kind of shoe I’d pick for a 100-mile ultra, but for shorter ultras, marathons, or even half marathon trail races, it felt spot on. The ride was responsive and snappy, and the plate made climbs and descents feel more efficient. I noticed that the wide platform and solid traction kept me confident even on technical singletrack. For me, it excelled as a go-to shoe for any trail run where I wanted to pick up the pace and really feel quick on my feet.
Conclusion
The Brooks Catamount 4 is a lightweight, responsive trail shoe built for speed and efficiency. With its breathable upper, energetic DNA FLASH v2 midsole, and grippy TrailTack outsole, it’s perfectly suited for trail races, faster training efforts, or any run where agility matters. It’s not the most cushioned option for super-long ultras, but that’s not its job—it’s built to help you move fast and stay confident on varied terrain. For me, it felt like a trail shoe that makes running feel effortless when I want to push the pace and cover ground quickly.
