There’s also a small Zoom Air unit in the forefoot of the Structure 24 which is only situated under the ball of the foot and doesn’t cover the entire forefoot like in the Vomero 16 and the Pegasus 38. All the rubber weighs down the shoe but this is one of the most durable outsoles to come out this year and I’ll be really surprised if it doesn’t get to over 1000 kilometres.

One thing I would agree on, is that for the first mile the shoes need some warm-up. After that, i usually feel like I’m running on clouds. Initially, I felt the midsole was on the firm side but satisfactory. After putting over 100 miles in them, I can honestly say they just get better with age. This is no more of a stability shoe than the Pegasus, or the Vomero is. The only thing that it shares in common with previous Structures is the name. Forget everything you previously knew about the Structure series because the Structure 23 is unlike any other Structure shoe to date.The word that describes the ride of the Structure 24 best is “balanced”. It feels well-cushioned without being mushy or firm and it falls into the same category as shoes like the ASICS Cumulus, Brooks Ghost and Hoka Clifton– versatile trainers that can fill the role of 2 or 3 shoes in your rotation. The Zoom Structures absorbed the impact of my feet hitting the ground nicely but failed to return any bounce. After a while, I felt my legs and feet tire because I was fighting the shoe. The densities of the lateral and the medial sides are the same but the wall of the medial side is just much higher. Inward rolling of the foot is controlled by making the medial side more cushioned than the lateral side. When I say breathable, I run in sunny Las Vegas, and I’m telling you, the uppers ventilate nicely on those sweaty runs. Soles that politely grip the road

If you’re in between sizes: for a tight fitting, go for the smaller size OR for a looser fit, then go up a size. Men’s Shoe Sizing UK However, the Zoom Structures were average, at best. Yes, I was able to log my miles, but the sole unit was too firm and the upper too washy.

Imagine if ASICS removed the firm medial post from the Kayano and gave it a single-density midsole. That’s exactly what they did with the Kayano Lite but at least they still kept the regular Kayano for runners who still want traditional stability. It does however shine on recovery or long runs at relaxed speeds. Slow runs from 15km up to marathon distances are in its wheelhouse.

The problem, however, is that looks alone do not make a shoe. The sole unit was too firm, unresponsive and it took a couple of miles on every run to feel comfortable running in them. After the Invincible Run, the Structure 24 is the next softest trainer in the Nike performance range. If you find the Invincible Run too unstable, expensive or fragile, the Structure 24 is a great alternative.Responsiveness is good in the forefoot because of the Zoom Air unit but is less responsive in the soft heel. There is a shallow cavity under the heel which adds a bit more responsiveness. A lot of runners stay away from “stability” shoes because it usually means firm, heavy and “poking arch” sensation. There’s a good reason that true stability shoes are a dying breed. It took 1.5 to 2 miles on each run before I began to feel comfortable. It almost felt as if the sole unit never truly broke in, as my feet had to adjust to the shoe on every run.. The whole shoe was stiff, but especially the sole. As a stability runner the structure provided by the upper helps hold your foot in place while you stride, and this is important. I stopped and retie my shoes thinking it was the laces being loose. I took off again but the heel was still loose and my midfoot hurt because the shoes were tied too tight.

Remember when Nike led us to believe that the Structure was being discontinued because they compared the React Infinity Run to it and said that the React Infinity Run caused runners fewer injuries than the Structure 22? If you already have the Structure 23, the Structure 24 is a version that you can skip. If you don’t have the Structure 23, the two versions are so similar that you can save money and get the 23 instead of the 24. Version 23 is lighter and has exactly the same ride as version 24. If the heel were lower to the ground, giving a more grounded feel and platform, it would help provide more support and stability. This feeling of unbalance became more evident the longer I ran. The structure uses a multi-thread that gives grip but still lets you rip. The treads don’t have aggressive lugs that get in the way of the road. Is your closet getting a little crowded with all those specialty shoes you’ve been collecting? It’s true, right?On the midfoot, the light green “Cucumber” coloured material can be seen through the large perforations.
