Nike Structure 25 First Run Review: A Stable, Cushioned Daily Trainer

Introduction

The Nike Structure 25 is a support shoe built for comfort and stability over long distances. It is the 25th generation of the line, and this update leans into boosted cushioning and support rather than speed. After putting in the early miles, here is how it shapes up as a supportive daily trainer for easy running.

Specs at a Glance

The Structure 25 has a bigger stack than its predecessor: 37.7mm in the heel and 27.7mm in the forefoot, giving a 10mm drop compared with the 8mm drop on the Structure 24. It is also heavier, weighing 10.7 ounces (304 grams) in a UK men’s size 8.5 test shoe. Price-wise, expect around $130 in the US.

What’s New in the Structure 25

Nike designed this shoe as a stable, comfortable runner for long distances. The midsole uses a higher stack of updated Cushlon 3.0 EVA blended foam, which Nike says brings better energy return and a softer ride, with more of that foam than before.

Support comes from enhanced arch support aimed at runners who tend to overpronate. If you want a stable platform for easy mileage, that is clearly the focus here.

Design and Upper

Up top there is a single-layer mesh that Nike claims improves breathability, though in practice it feels fairly dense and structured. The heel collar and tongue are very well padded, and this is anything but a minimal shoe. A substantial, narrow heel counter locks the heel in place and holds it firm.

Flip the shoe over and you get a generous covering of outsole rubber, with waffle-style lugs across the main midfoot and forefoot section and additional grip patterns on the lateral side. That all points toward good durability.

Fit

Running in a UK 8.5, the usual running shoe size, the fit was spot on: snug and secure but not too restrictive, with good heel hold. Going true to size is a sensible recommendation based on the first runs.

How It Runs

The early miles, roughly 15 so far, were mainly on tarmac with some uneven river path to test stability, largely at slower paces with a few faster interval sessions mixed in. The Cushlon cushioning has good volume and soaks up a lot of road and bumps, and there is some response, more if you land toward the forefoot. But it runs firmer than many recent big-stacked cushioned daily trainers, so you need to enjoy a firmer ride.

Compared with its closest neutral sibling, the Nike Vomero 17, you notice the lack of the ZoomX foam layer that adds more pop to that shoe. There is no escaping that this is a heavy shoe, and at times the ride felt a little slappy and clumpy, with sluggish transitions. The flip side is that firmness and slower transitions boost stability, which may be exactly what some runners want.

The ride clearly fits the easy-mileage bracket rather than faster running; it did not perform well at quicker paces. The plush heel collar keeps the heel counter at bay, but the upper felt a bit hot in early runs, and breathability was not great despite the claims.

First Verdict: Who Should Buy It

This is not a shoe for runners chasing a light, energetic feel. It is too heavy, response is limited, and even for someone who likes firmer shoes, it can feel like hard work at slower paces. You stay aware of it on the foot rather than letting it disappear.

But if you want a firmer ride in a stable easy-run shoe, a more subdued response that aids stability over longer runs, and you do not mind a bit of extra weight, this could be a good match. The support is there in spades, the platform is genuinely stable, and durability looks like a real strength given the rubber coverage. For an easy clip-along shoe with good stability, it is a solid option.

Conclusion

The Nike Structure 25 is a heavy, stable, firmer-riding trainer built for long, slow mileage. It will not win over runners who want pop and lightness, but for overpronators and easy-run specialists who value a secure platform and likely durability, it does its job well.
