THE SHORT ANSWER
The Brooks Cascadia 18 replaced the Cascadia 17 in August 2024 and changed as little as any Cascadia handoff on record. Same DNA Loft v2 foam for the third generation running, an outsole Brooks itself left mostly alone, a new mesh upper, and a small weight cut. One Believe in the Run tester accused Brooks of rolling out the exact shoe as last year, and the scores agreed.

Stay on your shoe, or switch?
Faithful successorThe nadir on the running side, and the shoe that made the community write the line's obituary. Nothing material changed except the upper, the foam entered its third year, and RunRepeat scored it 74 while flagging concerning wear. The Reddit thread that followed was titled The Death of a Once-Great Shoe, and its comments single the 18 out by name. Then the asterisk, which is becoming this line's signature: among PCT women that season the 18 was the highest-rated shoe on the entire trail at 8.50, ahead of the Lone Peak. The runners and the hikers were reviewing different shoes that happened to share a name.
Stick with the Cascadia 17 if
- Your 17s work, because underneath the upper this is the same shoe with a year less shelf time
- You side with the tester who found the redone fit worse rather than better
Move to the Cascadia 18 if
- You want the small weight cut on an otherwise identical platform
- You hike more than you run: this generation kept winning with thru-hikers even as runners left
Where the Brooks Cascadia is now
The line has moved three versions past the Brooks Cascadia 17, and the current model is now the Cascadia 20 (2026). Measured against your shoe:
- The Cascadia 20 is 0.5 oz lighter
- 5 mm more heel stack
- Drop moved from 8 mm to 6 mm
- New midsole foam
- List price up $20
What loyalists said about the update
The most explicit generational grief in the line. From the Death of a Once-Great Shoe thread: I despise the 18s, after a run or hike my feet were always super sore, I miss the feel of the Cascadia 15 and 16. Another commenter, three weeks into ownership: sounds like I dodged a bullet. The GTX aggregate sits at 64 percent, the lowest of the modern generations, and the Zappos distribution shifted from five-star-heavy to four-star-heavy, mild disappointment across the board rather than polarization. Meanwhile PCT women rated it the best shoe on trail. Both are true; they are different customers.

Beyond the Cascadia 18, these come closest to what the Cascadia 17 did.
- 10.4 oz
- 0 mm drop
- 25 mm heel
- $140 list
The two default thru-hiking shoes, and the cleanest philosophical split in trail running. The Lone Peak is zero drop, foot-shaped and low to the ground; the Cascadia runs a conventional taper, a 6 to 8 mm drop and a rock plate. Hikers cross-shop them constantly and the surveys disagree by trail: the Lone Peak owns the AT by wear count while the Cascadia out-rates it on the PCT. Moving between them means relearning your stride, not just your size.
Against your Brooks Cascadia 17: 0.9 oz lighter, 8 mm less heel stack, 8 mm less drop.
- 9.6 oz
- 5 mm drop
- 40 mm heel
- $165 list
The two mainstream technical-trail workhorses. The Speedgoat carries more foam on a 5 mm drop with Vibram Megagrip; the Cascadia sat lower with a rock plate and Brooks rubber until the 20 adopted Megagrip itself and dropped the plate, which moves the two closer than they have ever been. The Speedgoat still locks the foot down harder; the Cascadia still fits wider feet, in an actual 2E.
Against your Brooks Cascadia 17: 1.7 oz lighter, 7 mm more heel stack, 3 mm less drop, $25 more at list.
- 9.5 oz
- 8 mm drop
- 42 mm heel
- $155 list
Adjacent jobs rather than the same one. The Challenger is the door-to-trail cruiser, happiest on gravel and smooth singletrack; the Cascadia is the all-terrain protector, built around a rock plate and a rand for ground the Challenger reads through its soft midsole. Owners who split their miles between pavement and trail lean Challenger; owners who load a pack or point at rock lean Cascadia.
Against your Brooks Cascadia 17: 1.8 oz lighter, 9 mm more heel stack, the same drop, $15 more at list.
Questions runners ask
- Is the Brooks Cascadia 17 still available?
- Partially. Men's sizes still turn up on Amazon, but women's stock is gone. If your size shows up, decide quickly; discontinued stock only shrinks.
- Is the Cascadia 18 a downgrade from the Brooks Cascadia 17?
- No. The Cascadia 18 keeps the same ride and fixes small things. If you liked the Brooks Cascadia 17, the update carries over without an adjustment period.
- How much lighter is the Cascadia 18?
- 0.4 oz lighter in a men's US 9: 10.9 oz against the Brooks Cascadia 17's 11.3 oz.
- Is the Brooks Cascadia still made?
- Yes. The current version is the Brooks Cascadia 20, released in 2026, 3 versions on from the Brooks Cascadia 17.
- What is the closest current alternative to the Brooks Cascadia 17?
- The Altra Lone Peak 9. The two default thru-hiking shoes, and the cleanest philosophical split in trail running. The Lone Peak is zero drop, foot-shaped and low to the ground; the Cascadia runs a conventional taper, a 6 to 8 mm drop and a rock plate. Hikers cross-shop them constantly and the surveys disagree by trail: the Lone Peak owns the AT by wear count while the Cascadia out-rates it on the PCT. Moving between them means relearning your stride, not just your size.
