Is the Nike Structure 24 still available?

For now. Amazon still lists the Nike Structure 24, but the size run is thinning and prices swing with remaining stock. If your size is there, this is the late window, not the early one.

Is the Structure 25 a downgrade from the Nike Structure 24?

Not a downgrade, but a different shoe. The Structure 25 scores well with new buyers while changing the ride that Nike Structure 24 loyalists bought it for. Read the spec changes before assuming it will feel familiar.

How much lighter is the Structure 25?

0.3 oz lighter in a men's US 9: 10.7 oz against the Nike Structure 24's 11 oz.

Did the drop change from the Nike Structure 24 to the Structure 25?

Yes, from 8 mm to 10 mm. A drop change this size affects where your foot loads at landing, so plan a few easy runs to adapt.

Is the Nike Structure still made?

Yes. The current version is the Nike Structure 26, released in 2025, 2 versions on from the Nike Structure 24.

What replaced the Nike Structure 24?

THE SHORT ANSWER

The Structure 25 replaced the Structure 24 in fall 2023 and rebuilt the shoe: a much taller, softer platform, drop up from 8 to 10 mm, and a new Midfoot Support System sidewall and heel clip that put the word stability back in Nike marketing. The price rose $20 to $140.

Stay on your shoe, or switch?

Changed character

The 25 rebuilt the Structure into a taller, softer, more modern shoe and put stability back on the label, with sidewalls and a heel clip doing the work a medial post used to. Reviewers called it a breath of life for the series. It is still not the firm, posted Structure of the early era; that shoe ended with the 22.

Stick with the Structure 24 if

You want the lower, firmer 8 mm platform; the 25 is taller and softer
Sidewall support never convinced you and the 24's ride felt planted enough

Find Structure 24 stock

Move to the Structure 25 if

You want real support cues back; the sidewall and heel clip work
The 24 felt harsh and dated; the 25 is the softer, modern shoe

What loyalists said about the update

Mostly relief. Doctors of Running called the improved guidance a breath of life for the series, while two of its own reviewers argued it still reads as a slightly stabilized neutral. RoadTrailRun filed it under conservative, functional, boring trainer, and meant it kindly.
