THE SHORT ANSWER
Whichever your size still exists in. The Cascadia 18 is discontinued at retail, so remaining pairs sell against a thinning size run, while the Cascadia 19 has a full one. The Cascadia 18 also lists $10 lower.

Every spec, side by side
| Spec | Cascadia 18 | Cascadia 19 |
|---|---|---|
| FIT AND WEIGHT | ||
| Weight | 10.9 oz | 10.8 oz |
| RunRepeat's same-scale pair, which calls the change negligible; Believe in the Run's men's 9 came in at 10.5, a clearer cut. Either way the 19 stopped the line's weight creep without giving up 4 mm of new forefoot foam. | ||
| Widths | D, 2E | D, 2E |
| Upper | Lightweight engineered mesh with thermoplastic overlays | Mesh with a fully gusseted tongue |
| CUSHIONING GEOMETRY | ||
| Heel stack | 33 mm | 35 mm |
| Plus 2 mm at the heel and 4 at the forefoot, which is also how the drop fell from 8 mm to a quoted 6. One caution on that drop figure: RunRepeat's calipers read 7.8 mm against the claimed 6, the largest quoted-versus-lab gap in the line, so the real geometry change is smaller than the spec sheet implies. | ||
| Forefoot stack | 25 mm | 29 mm |
| Drop | 8 mm | 6 mm |
| MATERIALS | ||
| Midsole | DNA Loft v2 | DNA Loft v3, supercritical |
| The change three years of owners had asked for. RunRepeat measured energy return rising from 54.1 to 59.4 percent at the heel and 57.1 to 60.4 at the forefoot, the first real foam gain in the modern line. | ||
| Plate | Trail Adapt plate | TrailAdapt plate, articulated |
| VALUE | ||
| List price at launch | $140 | $150 |
| OTHER CHANGES | ||
| Rock plate | Trail Adapt plate | TrailAdapt plate, redesigned to flex and articulate |
| Same name, more compliant part. Road Trail Run credits it with the 19 losing the plank-like feel that dated the 17 and 18. | ||
| Fit | Toebox width 75.2 mm | Toebox width 72.5 mm |
| RunRepeat's calipers found the 19's toebox 2.7 mm narrower than the 18's, worth knowing in a line whose wide fit is half the appeal. The 2E remains, despite one review claiming otherwise. | ||

Questions runners ask
- Which is lighter, the Brooks Cascadia 18 or the Cascadia 19?
- Neither by a meaningful margin. Both weigh about 10.9 oz in a men's US 9.
- Did the price change between the Brooks Cascadia 18 and the Cascadia 19?
- Yes. List price went up $10, from $140 to $150. Street prices differ: the older shoe usually sells under list once its successor ships.
- Do the Brooks Cascadia 18 and Cascadia 19 come in the same widths?
- Yes. Both run in D, 2E for men's sizes, so a width that fit in the Cascadia 18 carries over to the Cascadia 19.
- How do the stack heights compare?
- 33 mm heel and 25 mm forefoot on the Brooks Cascadia 18, against 35 mm and 29 mm on the Cascadia 19. That is 2 mm more under the heel and 4 mm more under the forefoot. See the stack height note in the table above: the published figures changed convention mid-lineage.
- Is the Cascadia 19 still the newest Cascadia?
- No. The Cascadia 20 replaced it in 2026, so the Cascadia 19 now sells as an older model and usually below its $150 list price.
