Brooks Cascadia 16 Review: A Bold Remodel of a Trail Classic

Introduction

Brooks has rebuilt the Cascadia from the ground up. The 16 replaces the 15 with a new midsole compound, a reworked rock shield, a deeper lug pattern and a wider platform, and it is one of the most substantial remodels the long-running trail franchise has received. After 30-plus miles on a mix of trails, including some genuinely technical terrain, this is the most exciting version of the Cascadia to date.

For context, the shoe is clearly aimed at runners who want an all-year, all-terrain trainer rather than a race-day specialist. It is the kind of shoe you can wear through wet British winters and still trust on drier, rockier ground.

Who This Product Is for

The Cascadia 16 suits trail runners who want a single, dependable shoe for most types of terrain throughout the year. It is also a strong match for runners who have always found trail shoes too constricting: the fit is generous, with good width in the toe box and a roomy midfoot. Runners with high-volume or wider feet should feel right at home.

Conversely, if you have a narrow foot or a shallow midfoot and you want a locked-in, connected feel at speed on technical ground, this is the one area worth thinking carefully about before buying.

Main Strengths

Cushioning

The midsole now uses Brooks’ DNA Loft v2 compound with an extra 2mm of cushioning depth underfoot. Brooks claims it is 5% softer and 20% lighter than the previous version. In practice, the ride is plush but not overly soft: there is still a nice balance between comfort and connection to the trail. Previous Cascadias often felt firm on longer training runs, and this extra plushness is a big step forward.

Outsole and Grip

The outsole has been dramatically beefed up, with deeper, more aggressive lugs on a wider midsole profile. The lugs retain Brooks’ sticky TrailTack rubber, which has historically delivered a consistent grip across most surfaces, and in testing it was confidently grippy even in the wettest and muddiest conditions. It is genuinely an all-year outsole.

Protection and Upper

The updated ballistic rock shield with vertical flex grooves offers solid underfoot protection without compromising midsole flexibility, so the shoe still adapts to uneven ground. The new engineered monoloop 3D-printed upper is breathable and quick-drying, with sensible padding at the collar and tongue, a gusseted tongue for midfoot hold, structural overlays for durability, a toe bumper, an elastic lace-stow strap and a gaiter attachment. Drainage ports let water escape quickly, which is ideal for wet trail conditions.

Things to Consider Before Buying

The headline trade-off is fit. The shoe is wide, and not just at the toe box: the midfoot is roomy too. On flat trails this caused no problems at all, but on more technical terrain, including testing in Chamonix, the upper did not fully lock the foot in, with a little lateral and medial slippage despite the gusseted tongue. It is not a dealbreaker for steadier running, but fast, technical running exposes the looseness for narrow-footed runners.

It could also be a touch lighter. At 320g in a men’s UK 9.5 and 269g in a women’s shoe, it does not feel heavy, but there is room to shave more. And the bright yellow, red and black colorway will not be for everyone, though more subtle options exist.

Buying Advice

At £120 in the UK, the Cascadia 16 went through a substantial remodel without a price increase, which makes it good value for an all-terrain, all-year trainer. If you like a deep lug, a cushioned midsole that is not too soft, and a roomy fit, it should be near the top of your list. Comparable options with a similar deep-cushioned, grippy profile include the Hoka Mafate and the Saucony Exodus 11.

If you run in gaiters, the built-in attachment is a genuinely handy addition for wet and wintry conditions.

Conclusion

The Cascadia 16 is the best version of this shoe so far. Brooks has invested real development time here, and it shows: plusher cushioning, a far more capable outsole, good protection, and a comfortable, breathable upper. The wide fit is a genuine limitation for narrow-footed runners who want a locked-in feel on technical ground, but for everyone else this is now a trail shoe that competes properly with the rest of the market rather than merely getting by. It earns a solid recommendation as an all-year, all-terrain choice.
