The Gel-Nimbus 24, by 0.7 oz in a men's US 9 (10.2 oz vs 10.9 oz).

Did the price change between the Asics Gel-Nimbus 23 and the Gel-Nimbus 24?

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 Asics Gel-Nimbus 23 and Gel-Nimbus 24 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 23 carries over to the Gel-Nimbus 24.

No. The Gel-Nimbus 25 replaced it in 2023, so the Gel-Nimbus 24 now sells as an older model and usually below its $160 list price.
