Which is lighter, the Adidas Adizero Adios 7 or the Adizero Adios 8?

The Adizero Adios 8, by 0.4 oz in a men's US 9 (7.2 oz vs 7.6 oz).

Do the Adidas Adizero Adios 7 and Adizero Adios 8 come in the same widths?

Yes. Both run in D for men's sizes, so a width that fit in the Adizero Adios 7 carries over to the Adizero Adios 8.

How do the stack heights compare?

32 mm heel and 24 mm forefoot on the Adidas Adizero Adios 7, against 28 mm and 20 mm on the Adizero Adios 8. That is 4 mm less under the heel and 4 mm less under the forefoot. See the stack height note in the table above: the published figures changed convention mid-lineage.

Is the Adizero Adios 8 still the newest Adizero Adios?

No. The Adizero Adios 9 replaced it in 2025, so the Adizero Adios 8 now sells as an older model and usually below its $130 list price.

FIT AND WEIGHT
Weight	7.6 oz	7.2 oz
	The lightest Adios yet at launch.

	Fixed both of the 7's complaints, and fits roomier than the vice-grip 4/5 era.
CUSHIONING GEOMETRY
Heel stack	32 mm	28 mm
	A real reduction, not a convention change: RunRepeat's like-for-like calipers read 31.6 down to 28.0. The flat geometry started coming back here.

OTHER CHANGES
Plate	Thermoplastic Torsion shank	Energy Torsion Rod 2.0
	The three-pronged nylon rods that snap the slower heel through transitions, and the part the 9 would famously delete.
