Which is lighter, the Brooks Cascadia 19 or the Cascadia 20?

Neither by a meaningful margin. Both weigh about 10.8 oz in a men's US 9.

Did the price change between the Brooks Cascadia 19 and the Cascadia 20?

Yes. List price went up $10, from $150 to $160. Street prices differ: the older shoe usually sells under list once its successor ships.

Do the Brooks Cascadia 19 and Cascadia 20 come in the same widths?

No. The Brooks Cascadia 19 came in D, 2E; the Cascadia 20 runs in D. If you need 2E, remaining Cascadia 19 stock is your only option in this line.

How do the stack heights compare?

35 mm heel and 29 mm forefoot on the Brooks Cascadia 19, against 38 mm and 32 mm on the Cascadia 20. That is 3 mm more under the heel and 3 mm more under the forefoot. See the stack height note in the table above: the published figures changed convention mid-lineage.

Is the Cascadia 20 still the newest Cascadia?

Yes. The Cascadia 20 is the current Brooks Cascadia, listing at $160 at launch.

THE SHORT ANSWER

Whichever your size still exists in. The Cascadia 19 is discontinued at retail, so remaining pairs sell against a thinning size run, while the Cascadia 20 has a full one. The Cascadia 19 also lists $10 lower.

Every spec, side by side

Spec	Cascadia 19	Cascadia 20
FIT AND WEIGHT
Weight	10.8 oz	10.8 oz
Widths	D, 2E	D
Upper	Mesh with a fully gusseted tongue	Engineered mesh
CUSHIONING GEOMETRY
Heel stack	35 mm	38 mm
	RunRepeat's calipers say the gain is real, 34.8 to 37.9 mm at the heel, and its measured drop of 8.8 mm against the quoted 6 continues the line's pattern of understating drop. Between the taller stack and the plate deletion, the 20 protects with foam where every earlier Cascadia protected with structure.
Forefoot stack	29 mm	32 mm
Drop	6 mm	6 mm
MATERIALS
Midsole	DNA Loft v3, supercritical	DNA Flash v2, nitrogen-infused
	The second new foam in two years after three years of none. DNA Flash v2 comes from Brooks's race side, and it carries a quoted 38/32 stack at the same weight as the 19.
Plate	TrailAdapt plate, articulated	None
VALUE
List price at launch	$150	$160
	A second consecutive $10 step; the line has risen $30 since the 18.
OTHER CHANGES
Outsole	TrailTack Green, 25 percent recycled, ~4 mm lugs	Vibram Megagrip, 4 mm chevron lugs
	The first non-Brooks rubber in Cascadia history, and the single most requested change in the line's reviews. It puts the Cascadia on the same outsole as the Speedgoat and the Timp.
Rock plate	TrailAdapt plate, redesigned to flex and articulate	None
	The plate lineage that ran from the Ballistic Rock Shield through TrailAdapt ends here; RunRepeat's teardown found no plate and judged the foam thick enough to justify it. One caveat: the 20's sidewall still prints Trail Adapt branding, so Brooks considers the system alive as marketing even with the plate gone.
Platform width	105 mm heel, 90 midfoot, 125 forefoot	95 mm heel, 80 midfoot, 115 forefoot
	Road Trail Run's measurements: a centimetre narrower at every station, on the line whose wide platform and 2E fit were half the constituency. The wide-fit question is the one to watch as reviews land.

Weighing whether to switch at all, rather than which of these two to buy? What replaced the Brooks Cascadia 19 covers the verdict on the update, what loyalists made of it, and the closest alternatives from other brands.
