Brooks Cascadia 19 Review & Sizing Guide

Published Updated

Buy the Cascadia 19 for moderate-to-technical trail running with the line's most cushioned ride and best stability across rocky descents; skip if you specifically loved the 18's gaiter strip and aggressive lugs, because the 19 trades both for a road-ier ride they swapped out the laces for what feels like thick twine... they got rid of the velcro strip for gaiters.

Full breakdown

Brooks Cascadia 19 is the 2025 revision of the brand's longest-running trail flagship: more cushioning than the 18, redesigned lugs, twine-style laces and heel pull replacing the previous webbing, and a deliberately tighter heel hold. Owners are divided — some call it the line's best yet with confidence on rocky desert trails, others mourn the lost gaiter strip and shallower lugs v19 has been fantastic on the rocks in AZ - reasonably light, pretty resilient, no issues with stability. Buy it for moderate-to-technical day-hike and trail-running terrain; skip it if you owned the 18 for the gaiter strip and deep lugs.

FAQ

Cascadia 18 vs 19 — which should I buy?

Buy the 19 if you want more cushion and improved descent confidence on rocky trails; stay with the 18 if you depend on the gaiter velcro strip and deeper lugs for muddy or burry trails. The 62-comment 'Death of a Once-Great Shoe' thread is explicit that the 19 lost the velcro gaiter strip and the lugs got shallower, which are the two biggest spec downgrades they swapped out the laces for what feels like thick twine. The heel loop at the back is also now thick twine, and it's a smaller loop. Choose by terrain: rocks and packed trail favor 19, mud and burrs favor 18 (or DIY velcro on the 19).

How do I size the Cascadia 19 with wide feet?

Order the wide width if available, because multiple reviewers describe the 19 as narrower than the 18 despite Brooks's standard width offering. The 41-comment review thread has wide-foot runners specifically asking whether to size up or buy wide because of online reviews describing the 19 as narrow I also have wide feet. Did you order the wide size? I just watched a review of the C19 where they described them as narrow. Buy the wide if you bought the 18 in wide; the brand's wide widths are the cleanest way to recover the 18 fit in this generation.

Is the Cascadia 19 good for 100K and ultra distances?

Yes, multiple owners ran 100K in the Cascadia 19 successfully with the more cushioned midsole holding up across the day. The 'death of' thread coexists with a top comment that this is the best trail shoe the runner has ever used, completing a first 100K in them on mostly technical terrain I've been a Cascadia fan since they launched... I completed my first 100k in them on mostly technical terrain. Buy with confidence for 50K-100K race day if you fit the standard width; the caveat is lace-bite-driven blister risk under the middle toes when laces clamp down hard on long descents, so pair with quality socks and retie at the halfway point.

Do I lose deep-mud capability with the Cascadia 19?

Yes, the lugs are noticeably shallower than the 18 and you give up some deep-mud bite for the more cushioned road-style ride. The 'Death of' review specifically calls out that the lugs look much shallower than the 18s and predicts faster tread replacement the treads/lugs look much shallower than the 18s, so you're def gonna need to replace them sooner. Choose the Cascadia 19 for the dry/hardpack 80% of trail running; if mud is your terrain reality, look at Saucony Peregrine or Hoka Speedgoat instead.

Is the Cascadia 19 worth retail at $140?

Yes at retail if you do moderate-to-technical day hikes and trail runs and want long-term cushioning; the price is fair for the line's lineage and Brooks's outsole investment. The community is split: the 'death of' thread is 62 negative comments while the announcement thread is 41 mostly positive ones, which is the buyer signal that the 19 polarizes existing owners v19 definitely a bit more cushioned as the 18, seemingly bridging between older Cascadias and the Caldera. Wait for sale only if you have a working trail shoe; sale windows on Cascadia are predictable around model transitions.
