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. Stability is high even though there is no firmer wedge or medial post. This is due to two main reasons:

On the medial side, the midsole is built up more than on the lateral side so there is a noticeable level of under-arch support without the firm poking sensational.I used my Structure 24 for mainly easy, middle distance runs which is what it feels most comfortable doing although it is capable of slightly faster efforts. The best thing about the Structure 24 is that it doesn’t feel like a firm, stiff stability trainer that pokes your arch. It’s a comfortable, stable and versatile trainer which can handle most runs. 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. My first run was 15 kilometres at an easy pace. The first thing that surprised me was how much cushion the midsole had.

The Structure 24 can be used as your daily trainer, recovery trainer, or long run shoe. It’s not the best shoe for speed work because of its flexible forefoot and its plush upper which makes it weighty. The Structure 24 definitely isn’t as stable as the Structure 22 and Structures before the 22 because of how much softer its midsole is but it’s still an incredibly stable ride and one of the most stable neutral shoes you can buy. The Zoom Air bag in the forefoot of the Structure 23 is similar to the setup in the Pegasus 33/34 where you could feel the air bag through the strobel lining and the insole. 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. Upon opening the box, I was extremely impressed with the colorway and design of the shoe. The navy blue mixes well with the orange-peel swoosh and the crimson flash heel.Consider coming into a store and doing a video gait analysis. Gait analysis monitors your body’s movement and your feet (sports biomechanics) whilst running. It’s commonly used to help athletes run more efficiently and to identify movement related problems for people with injuries who are seeking new running shoes. 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. It’s very important to know your running gait so that we can advise and fit the correct shoes according to your own individual requirements. Can’t get into store? Try a wet foot test
