Which is lighter, the Saucony Peregrine 12 or the Peregrine 13?

The Peregrine 13, by 0.6 oz in a men's US 9 (9.2 oz vs 9.8 oz).

Did the price change between the Saucony Peregrine 12 and the Peregrine 13?

Yes. List price went up $10, from $130 to $140. Street prices differ: the older shoe usually sells under list once its successor ships.

Do the Saucony Peregrine 12 and Peregrine 13 come in the same widths?

Yes. Both run in D for men's sizes, so a width that fit in the Peregrine 12 carries over to the Peregrine 13.

How do the stack heights compare?

26.5 mm heel and 22.5 mm forefoot on the Saucony Peregrine 12, against 28 mm and 24 mm on the Peregrine 13. That is 1.5 mm more under the heel and 1.5 mm more under the forefoot. See the stack height note in the table above: the published figures changed convention mid-lineage.

Is the Peregrine 13 still the newest Peregrine?

No. The Peregrine 14 replaced it in 2024, so the Peregrine 13 now sells as an older model and usually below its $140 list price.

Every spec, side by side

Spec	Peregrine 12	Peregrine 13
FIT AND WEIGHT
Weight	9.8 oz	9.2 oz
	Believe in the Run's men's 9; RunRepeat's lab pair weighed 9.6. Either way the lightest Peregrine of the modern line.
Widths	D	D
Upper	Stripped-down mesh with TPU film at the forefoot and ripstop at the heel	Slimmer engineered mesh with a 3.5 mm tongue
	Doctors of Running measured the tongue at 3.5 mm against the Peregrine 11's 11 mm, which is the whole minimalist turn of this era in one number. They still called it the best-fitting Peregrine.
CUSHIONING GEOMETRY
Heel stack	26.5 mm	28 mm
	A real change for once, and the control case that shows Saucony can quote accurately when it wants to: RunRepeat's calipers read 27.5 and 23.6 mm against the quoted 28 and 24, a match within half a millimetre on every axis.
Forefoot stack	22.5 mm	24 mm
Drop	4 mm	4 mm
MATERIALS
Midsole	PWRRUN with a PWRRUN+ topsole	PWRRUN, softer formula, with a PWRRUN+ topsole
	A softer mix on 2 mm more foam, which together turned the sharpest complaint about the 12 into the 13's selling point.
Plate	Forefoot rock plate	Thin forefoot rock plate
VALUE
List price at launch	$130	$140
