love it! runs small & narrow
AnnikaR378630344Jun 04, 2026
Agree with the other comments - these do run small. I was a 9.5 in the Structure 25, but sized up to a 10 in these. I'm typically a true 9.5 and have a very narrow foot and high arch. I think stability shoes are so underrated - I first started running in 2023 regular running shoes but started getting ankle issues. I had no idea this could all be fixed by a shoe until I got properly fitted for my first stability sneaker. I was sold a stability shoe from a different brand, and the ankle pain went away but overall something was off about the shoe. When I wore those out, I decided to see what Nike had in store for a stability shoe and landed on the Structure 25. I think these shoes were made for me. I'm still a beginner runner - these are my only running shoes & I typically go for 3-7 mile runs, averaging 10 mi per week. I have had zero pains, and my ankles feel incredibly stable when I run. I will say - I am not a fast runner, and speed is not a concern for me. However, the Structure 26 feels slightly bouncier & less rigid than the previous version. It will be heavier than the top running shoes currently, but as far as stability shoes go it doesn't bother me. If you're looking for a narrow stability shoe - this is it.

FAQ (9)

Who is the Structure 26 best suited for?

The Structure 26 is best suited for runners who want a supportive daily trainer. It’s designed for road runners who prefer a guided feel underfoot and comfortable cushioning that feels smooth and stable through every stride.

What is the difference between a stability running shoe and a neutral running shoe?

Stability shoes add support features that help create a steadier, more guided ride through transition. Neutral shoes are designed to allow more natural movement with less added structure underfoot.

What cushioning and support technology does the Structure 26 use?

A full-length ReactX foam midsole delivers soft, responsive cushioning. It works with a midfoot support system that helps create a secure, stable feel through the arch and heel.

What is ReactX foam?

ReactX foam is a high-performance foam designed to feel soft, durable and 13% more responsive than previous React technology. It compresses on impact, rebounds quickly and helps keep the ride feeling energized underfoot.

How does the Structure 26 compare to earlier Structure models?

The Structure 26 offers more responsive cushioning than the Structure 25 thanks to the addition of ReactX foam and a higher stack height. The result is a smoother, more comfortable ride with the steady support Structure runners have come to count on. We also added high-abrasion rubber to the heel for increased durability compared to the 25.

What width options are available in the Structure 26?

The Structure 26 comes in Regular and Extra Wide, helping more runners find the right blend of support, comfort and room through the foot.

How does the Structure 26 fit, and how should runners size the Structure 26?

Most runners should start with their usual size. Runners who prefer extra room—especially for longer miles or thicker socks—may prefer going up half a size.
