THE SHORT ANSWER
The Structure 24 replaced the Structure 23 in fall 2021 and changed almost nothing: a plusher, slightly roomier upper, small internal tweaks that made the support a little more noticeable, and 0.8 oz more on the scale.
At a glance
- The Structure 24 is 0.8 oz heavier
- Drop is unchanged at 8 mm
- New midsole foam
Every spec side by side, with the reason behind each change: Structure 23 vs 24.
Stay on your shoe, or switch?
Faithful successorThe 24 is the 23 with a plusher upper and a little more heft. Doctors of Running graded it well and spent half the review arguing that Nike should just call it a stability shoe again. If the 23 worked for you, so does this.
Stick with the Structure 23 if
- The 23 fits and closeouts run cheaper; the platform is the same
- Every fraction of an ounce bothers you; the 24 gained 0.8
Move to the Structure 24 if
- You want the plusher, roomier upper
- You want the support cues slightly more noticeable in the same ride
Where the Nike Structure is now
The line has moved three versions past the Nike Structure 23, and the current model is now the Structure 26 (2025). Measured against your shoe:
- The Structure 26 is 0.2 oz heavier
- 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
Quietly appreciated. Reviewers praised the durability and value, called it a stable-neutral workhorse, and kept up the same complaint from the year before: heavy, a bit dated, and Nike still would not say the word stability.
