Choosing the perfect trail running shoe is essential for maximizing performance and preventing injuries. In this post, we’ll compare two popular options from Brooks—the Cascadia 18 and the Caldera 7. From cushioning and stability to fit and grip, this guide will help you decide which shoe is best suited for your trail running needs.
Cushioning: Balanced vs Plush
The Brooks Cascadia 18 features balanced cushioning with 33 mm in the rearfoot and 25 mm in the forefoot, resulting in an 8 mm drop. This design provides excellent responsiveness and control, making it ideal for technical trails.
On the other hand, the Brooks Caldera 7 offers a softer, more cushioned experience. With 39 mm in the rearfoot and 33 mm in the forefoot, its 6 mm drop and DNA Loft nitrogen-infused midsole deliver a plush, cloud-like ride. This makes the Caldera 7 perfect for long-distance runs and recovery days, prioritizing comfort over speed.
Stability: Rock Plate vs Sidewalls
Stability is a defining feature of both shoes, but they achieve it in different ways.
The Cascadia 18 includes a rock plate in the midsole, providing extra protection against sharp objects and stabilizing the foot on uneven surfaces. This shoe is built for rugged terrain, reducing flexibility for added support.
In contrast, the Caldera 7 features raised sidewalls that cradle the foot, along with a broad base that improves contact with the ground. Its stiff heel counter minimizes side-to-side movement, making it a reliable choice for downhill running and quick direction changes.

Grip and Traction
Both shoes are equipped with TrailTack Green outsoles, made with 25% recycled materials for durability and sustainability. However, their lug patterns differ:
- Cascadia 18: 4.5 mm multi-directional lugs provide superior grip on technical and muddy terrain.
- Caldera 7: 4 mm lugs are optimized for road-to-trail transitions, offering a smoother ride on flat surfaces but less aggressive traction on challenging trails.
If your runs take you across technical trails or wet surfaces, the Cascadia 18 is the better choice. For mixed terrain, including road sections, the Caldera 7 performs well but may wear down faster on asphalt
Fit and Comfort
When it comes to fit, the Cascadia 18 has a slightly tapered toe box, delivering a snug, racing-style feel that’s ideal for runners seeking precision on technical trails. In contrast, the Caldera 7 offers a roomier toe box, making it a better option for runners with wider feet or those who prefer extra space for long-distance comfort.
Both shoes come with a gusseted tongue, padded heel counter, and gaiter tabs, ensuring a secure and comfortable fit. Engineered mesh uppers provide breathability and durability, with overlays for added toe protection.
Which Shoe Should You Choose?
The Brooks Cascadia 18 is an all-around performer, excelling on technical trails with its balanced cushioning, protective rock plate, and superior grip. It’s versatile enough for various terrains and activities, making it a favorite among trail runners.
The Brooks Caldera 7, on the other hand, shines in long-distance and recovery runs. Its plush cushioning and added stability features make it perfect for leisurely outings or ultra-long runs. However, its heavier weight (approximately 300 grams for Men’s size 9 US) makes it less suitable for speed work or shorter, high-tempo runs.

Final Thoughts
Both the Cascadia 18 and Caldera 7 are excellent trail shoes, but their strengths cater to different needs. If you’re seeking a versatile, technical trail shoe, the Cascadia 18 is the way to go. If long-distance comfort and plush cushioning are your priorities, the Caldera 7 is a top choice.
