Neither by a meaningful margin. Both weigh about 6.8 oz in a men's US 9.

Do the Saucony Kinvara 14 and Kinvara 15 come in the same widths?

No. The Saucony Kinvara 14 came in D, 2E; the Kinvara 15 runs in D. If you need 2E, remaining Kinvara 14 stock is your only option in this line.

How do the stack heights compare?

31 mm heel and 27 mm forefoot on the Saucony Kinvara 14, against 29 mm and 25 mm on the Kinvara 15. That is 2 mm less under the heel and 2 mm less under the forefoot. See the stack height note in the table above: the published figures changed convention mid-lineage.

Is the Kinvara 15 still the newest Kinvara?

No. The Kinvara 16 replaced it in 2025, so the Kinvara 15 now sells as an older model and usually below its $120 list price.
