Neither by a meaningful margin. Both weigh about 10.8 oz in a men's US 9.

Did the price change between the Asics Gel-Kayano 30 and the Gel-Kayano 31?

Yes. List price went up $5, from $160 to $165. Street prices differ: the older shoe usually sells under list once its successor ships.

Do the Asics Gel-Kayano 30 and Gel-Kayano 31 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 30 carries over to the Gel-Kayano 31.

40 mm heel and 30 mm forefoot on the Asics Gel-Kayano 30, against 40 mm and 30 mm on the Gel-Kayano 31. Same platform under both.

Is the Gel-Kayano 31 still the newest Gel-Kayano?

No. The Gel-Kayano 32 replaced it in 2025, so the Gel-Kayano 31 now sells as an older model and usually below its $165 list price.
