Every spec, side by side
| Spec | Cascadia 15 | Cascadia 16 |
|---|---|---|
| FIT AND WEIGHT | ||
| Weight | 10.6 oz | 10.5 oz |
| Widths | D, 2E | D, 2E |
| Upper | Engineered mesh with printed overlays, gaiter attachments and a lace keeper | Reconstructed mesh with a wrap-around rand and expanded toe bumper |
| Where the dissenters focused. One decade-long Brooks loyalist described the new fit as a pinching patent leather dress flat and ended the review with I think I am done with Brooks. Others praised the roomier 2E. | ||
| CUSHIONING GEOMETRY | ||
| Heel stack | 31 mm | 33 mm |
| A real 2 mm of extra foam front and back, quoted on the same basis both sides. The drop held at 8 mm, where it had sat for the whole modern line. | ||
| Forefoot stack | 23 mm | 25 mm |
| Drop | 8 mm | 8 mm |
| MATERIALS | ||
| Midsole | BioMoGo DNA | DNA Loft v2 |
| Road Trail Run put the new foam at 5 percent softer and 20 percent lighter, and it carried a 2 mm taller stack without a weight penalty. This foam then stayed put for three generations, which becomes the line's next problem. | ||
| Plate | Ballistic Rock Shield on a four-point Pivot Post chassis | Ballistic Rock Shield, reshaped with vertical grooves |
| VALUE | ||
| List price at launch | $130 | $130 |
| OTHER CHANGES | ||
| Support system | Four-point Pivot Post chassis, two lateral and two medial | Reshaped Ballistic Rock Shield with vertical grooves |
| The grief, and the end of the design the Cascadia was named for. The pivot posts had steadied the shoe on off-camber ground since the early versions; Brooks bet that a grooved rock shield and wider geometry could do the same job with less weight. A Zappos reviewer confirmed the loss plainly: they still feel stable even though they no longer have the pivot posts. | ||
| Outsole | TrailTack, 4 mm multidirectional lugs | TrailTack, chevron lugs spaced for mud shedding, midfoot lugs removed |
| The first Cascadia outsole without midfoot lugs, a nod toward faster ground. | ||
Weighing whether to switch at all, rather than which of these two to buy? What replaced the Brooks Cascadia 15 covers the verdict on the update, what loyalists made of it, and the closest alternatives from other brands.

Questions runners ask
- Which is lighter, the Brooks Cascadia 15 or the Cascadia 16?
- Neither by a meaningful margin. Both weigh about 10.6 oz in a men's US 9.
- Do the Brooks Cascadia 15 and Cascadia 16 come in the same widths?
- Yes. Both run in D, 2E for men's sizes, so a width that fit in the Cascadia 15 carries over to the Cascadia 16.
- How do the stack heights compare?
- 31 mm heel and 23 mm forefoot on the Brooks Cascadia 15, against 33 mm and 25 mm on the Cascadia 16. That is 2 mm more under the heel and 2 mm more under the forefoot. See the stack height note in the table above: the published figures changed convention mid-lineage.
- Is the Cascadia 16 still the newest Cascadia?
- No. The Cascadia 17 replaced it in 2023, so the Cascadia 16 now sells as an older model and usually below its $130 list price.
