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 characterThe 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
Old stock is gone; see alternatives below.
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
Where the Nike Structure is now
Two updates on, the Structure 26 (2025) is what sits on shelves today. Against the shoe you own rather than the one that directly replaced it:
- The Structure 26 is 0.6 oz lighter
- 16 mm more heel stack
- Drop moved from 8 mm to 10 mm
- New midsole foam
- List price up $25
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.

The Adrenaline is the default comparison in nearly every Structure review, and it made the same transition Nike did, from a medial post to unobtrusive guidance. It runs a little softer, fits a little wider, and updates more predictably.

The GT-2000 is the parallel-universe Structure: it also deleted its medial post, but a year later and to applause instead of grief. It is softer with more width options; the Structure is the firmer, snappier ride.

Questions runners ask
- Is the Nike Structure 24 still available?
- Partially. Women's sizes still turn up on Amazon, but men's stock is gone. If your size shows up, decide quickly; discontinued stock only shrinks.
- 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 is the closest current alternative to the Nike Structure 24?
- The Brooks Adrenaline GTS 25. The Adrenaline is the default comparison in nearly every Structure review, and it made the same transition Nike did, from a medial post to unobtrusive guidance. It runs a little softer, fits a little wider, and updates more predictably.
