Which is lighter, the Asics Gel-Kayano 28 or the Gel-Kayano 29?

The Gel-Kayano 29, by 0.4 oz in a men's US 9 (10.5 oz vs 10.9 oz).

Do the Asics Gel-Kayano 28 and Gel-Kayano 29 come in the same widths?

Yes. Both run in D, 2E, 4E for men's sizes, so a width that fit in the Gel-Kayano 28 carries over to the Gel-Kayano 29.

How do the stack heights compare?

23 mm heel and 13 mm forefoot on the Asics Gel-Kayano 28, against 25 mm and 15 mm on the Gel-Kayano 29. That is 2 mm more under the heel and 2 mm more under the forefoot.

Is the Gel-Kayano 29 still the newest Gel-Kayano?

No. The Gel-Kayano 30 replaced it in 2023, so the Gel-Kayano 29 now sells as an older model and usually below its $160 list price.
