Brooks Cascadia 20 Review: Twenty Versions and Still Evolving

Twenty iterations in, the Brooks Cascadia 20 has a firmer midsole, a more streamlined fit and a livelier ride. Kate Dzienis heads out on her local trails to see how the latest version stacks up.

Twenty versions deep, and the Cascadia is still out here reinventing itself like a shoe with main character energy.

Brooks has given this one a glow-up: stack height climbs to a generous 38mm heel and 34mm forefoot, up 4mm on last year’s model, while the 6mm drop stays exactly where it’s always been.

I took these out across my usual trails that consisted of pea gravel, some fire trail and compact earth, and from the first run I was reminded why I keep coming back to Brooks time and again. This is a brand that has never once made my plantar fasciitis a topic of conversation. I don’t have to think about inserts, I don’t have to second-guess the arch support, I just lace up and go, which, if you’ve ever dealt with foot pain that dictates your entire shoe-buying life, is worth more than any spec sheet could possibly convey. And the fact this is a neutral shoe, and it still offers me support, says something.

The new DNA Flash v2 midsole swaps out last year’s plusher DNA Loft v3 for something firmer underfoot. Both foams are nitrogen-infused, which in practice means the ride doesn’t go soft and mushy on you just as your legs are starting to tire late in a run, a small but appreciated detail on longer outings.

On compact earth and gravel tracks, that firmness translates into a reactive, energetic ride, the kind that makes you want to pick up the pace rather than settle in. Climbs felt punchy and responsive, and I never once felt like the shoe was absorbing my effort rather than returning it. Descents also held their composure nicely, with none of that slightly unnerving compression you get from an over-plush midsole trying to catch up with your downhill momentum.

The heel is a standout for me, I’m all about the heel. Soft, well-cushioned, and exactly the kind of support that keeps my feet happy kilometre after kilometre without a hint of rubbing or pressure, especially when I wear my ankle socks. Paired with a standard tongue that sits comfortably without sliding or bunching, the whole upper experience feels dialed-in.

And can we talk about the laces? They’re bungee-style, exactly as they should be. I will die on this hill: once you’ve gone bungee, there’s no going back to fiddling with a bow mid-run, and Brooks clearly understands the assignment here, as they’ve also included an elastic lace keeper and I love those.

Visually, this might be one of my favourite colour line-ups Brooks has put out. There’s a sense that someone in the design room actually cares about aesthetics rather than just churning out the usual grey-and-neon combinations we’ve all become numb to, and in this shoe, whatever colourway you land on, you won’t feel like you’re wearing hazard tape or lacking personality.

When it comes to grip, I came away happy. The lugs aren’t the deepest or most aggressive I’ve run in (don’t expect elite performance here), but on moderate technical trail, they held their ground confidently and never once left me second-guessing my footing. I didn’t get a chance to test these in proper wet or muddy conditions, so I can’t speak on how they’d fare there, but for the terrain most of us are running on week to week, they’re more than decent.

Now, the honest bit, because every great shoe still has a limit. The narrower footprint, a full centimetre slimmer than the previous model, is a win on tighter single-track, but that firmer midsole does trade away a bit of ground feel; you’re relying on the shoe to smooth out roots and rocks rather than feeling your way over them yourself, and there are some people that like to feel everything under them.

The midfoot lockdown has also been tightened up nicely, giving a secure, held-in feel on uneven ground, though anyone with a higher-volume foot might notice the toe box has shrunk slightly alongside it. Worth trying on if you’re used to a roomier front end.

Available in a range of colours to suit all personality types, the Brooks Cascadia is a firmer, faster and more stable Cascadia that is brilliant on fire trail and compact earth, with grip that holds its own on moderate technical ground.
