Which is lighter, the Asics Gel-Kayano 27 or the Gel-Kayano 28?

The Gel-Kayano 28, by 0.2 oz in a men's US 9 (10.9 oz vs 11.1 oz).

Do the Asics Gel-Kayano 27 and Gel-Kayano 28 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 27 carries over to the Gel-Kayano 28.

How do the stack heights compare?

22 mm heel and 12 mm forefoot on the Asics Gel-Kayano 27, against 23 mm and 13 mm on the Gel-Kayano 28. That is 1 mm more under the heel and 1 mm more under the forefoot.

Is the Gel-Kayano 28 still the newest Gel-Kayano?

No. The Gel-Kayano 29 replaced it in 2022, so the Gel-Kayano 28 now sells as an older model and usually below its $160 list price.
