THE SHORT ANSWER
The Pegasus 40 replaced the Pegasus 39 in April 2023. It is a light retune rather than a redesign: same midsole, same dual Zoom Air units, with a softer upper that eased the 39's tight midfoot.

Stay on your shoe, or switch?
Faithful successorThe 40 rides so close to the 39 that most runners could not tell them apart blindfolded. Buy whichever one is cheaper in your size. That is not a knock. The 39 was good, and the 40 kept it.
Stick with the Pegasus 39 if
- The 39 fits you and sells cheaper; the two ride the same
- You prefer the slimmer, racier upper
Move to the Pegasus 40 if
- The 39's midfoot wrap felt tight on your arch
- Your size in the 39 is already gone
Where the Nike Pegasus is now

- Drop is unchanged at 10 mm
- New midsole foam
- List price up $15
What loyalists said about the update
Reaction was a shrug, in the good sense. Forum threads settled on a consistent line: the 40 is the 39 with a comfier upper and 0.3 oz of extra weight. Wide-footed runners appreciated the relaxed midfoot.

Beyond the Pegasus 40, these come closest to what the Pegasus 39 did.
- 10.2 oz
- 10 mm drop
- 36 mm heel
- $150 list
The Ghost is where Pegasus runners land most often. Similar weight, a little softer underfoot, and since the Ghost 17 the drop matches at 10 mm. It has no Zoom Air snap, but it fills the same do-everything role and Brooks changes it slowly.
Against your Nike Pegasus 39: 0.9 oz heavier, 3 mm more heel stack, the same drop, $20 more at list.
- 8.9 oz
- 8 mm drop
- 38 mm heel
- $145 list
The Ride matches the Pegasus in role and price, now with a softer supercritical foam. The main adjustment is the 8 mm drop, which heel strikers will notice for a week or two.
Against your Nike Pegasus 39: 0.4 oz lighter, 5 mm more heel stack, 2 mm less drop, $15 more at list.
- 9.2 oz
- 8 mm drop
- 42 mm heel
- $155 list
Runners leaving the Pegasus for something softer usually end up here. The Clifton is more cushioned with a much taller, rockered platform that changes how the shoe moves through a stride. Try it on first.
Against your Nike Pegasus 39: the same weight, 9 mm more heel stack, 2 mm less drop, $25 more at list.
