Which is lighter, the Asics Gel-Nimbus 25 or the Gel-Nimbus 26?

The Asics Gel-Nimbus 25, by 0.5 oz in a men's US 9 (10.2 oz vs 10.7 oz).

Do the Asics Gel-Nimbus 25 and Gel-Nimbus 26 come in the same widths?

Yes. Both run in D, 2E, 4E for men's sizes, so a width that fit in the Gel-Nimbus 25 carries over to the Gel-Nimbus 26.

How do the stack heights compare?

41.5 mm heel and 33.5 mm forefoot on the Asics Gel-Nimbus 25, against 41.5 mm and 33.5 mm on the Gel-Nimbus 26. Same platform under both.

Is the Gel-Nimbus 26 still the newest Gel-Nimbus?

No. The Gel-Nimbus 27 replaced it in 2025, so the Gel-Nimbus 26 now sells as an older model and usually below its $160 list price.
