Can I go straight from the Nike Pegasus 39 to the Pegasus 41 and skip the Pegasus 40?

Yes, but going Pegasus 39 to Pegasus 41 means taking one change in a single step: the Pegasus 41 is where the ride moved. Drop holds at 10 mm, so the difference is foam and fit rather than geometry: React foam with Zoom Air units under heel and forefoot to Full-length ReactX foam with Zoom Air units under heel and forefoot.

How much did the weight change across these two updates?

0.7 oz on in total, 9.3 oz to 10 oz in a men's US 9. The Pegasus 40 took it to 9.6 oz first.

Is the Pegasus 40 the better buy than either of these?

On paper it splits them: 9.6 oz against 9.3 oz for the Pegasus 39 and 10 oz for the Pegasus 41, on a 33 mm heel and a $130 list price. Whether that is worth chasing depends on what the Pegasus 40 update actually did, which the section above works through.

Did the Pegasus get taller between the Pegasus 39 and the Pegasus 41?

Heel stack went 33 mm to 37 mm, by way of 33 mm on the Pegasus 40. Drop held at 10 mm throughout, so the extra foam sits under both ends.

Where does the Pegasus 41 sit in the Pegasus lineup now?

Two versions on from the Pegasus 39, and already replaced itself: the Pegasus 42 arrived in 2026. If you are shopping old stock anyway, price the Pegasus 41 against it before deciding.

THE SHORT ANSWER

Two updates and 2 years separate the Nike Pegasus 39 from the Pegasus 41. Net change: 0.7 oz heavier, 4 mm more heel stack, a new midsole, $10 more at list. The Pegasus 41 is where the character changed, and that is the update Pegasus 39 owners notice first.

Or buy the Pegasus 40 instead?

The Pegasus 40 is the value play if you find it discounted. It carries most of what the Pegasus 41 added while selling as an older model, and moving one version at a time is the smaller adjustment.
