Start with the Structure family
Nike places Structure in its supportive road-running range. The useful distinction is between a model designed around guidance and a neutral trainer that happens to feel steady to a particular runner. A wide-looking heel, padded collar or soft foam alone does not establish that two shoes offer the same support.
Structure 26 uses ReactX foam and a support system around the midfoot, arch and heel. Those are construction details, not a promise that the shoe will correct every runner’s movement. Think of the model as a starting point for a daily-training fitting, then assess whether the shape and pressure suit you.
Where Structure Plus changes the choice
Structure Plus adds ZoomX cushioning alongside a ReactX carrier. That makes the decision more interesting than simply choosing the newest number: compare two cushioning approaches within the support family. More foam technology does not automatically make the Plus a better match for every distance or foot.
For a useful comparison, wear a complete pair of each model and repeat the same short route. Include your ordinary easy pace, a little walking and a few relaxed turns. Record whether the additional cushioning improves comfort or merely feels different. Avoid deciding entirely from how the shoes feel when you stand still.
Keep other Nike franchises in perspective
A neutral Nike shoe can be comfortable and sufficiently steady for you without becoming a Structure substitute on paper. If your existing neutral trainer works, there is no shopping requirement to replace it because a fitter or friend notices some inward foot movement. If it feels unpredictable, describe when that happens before changing categories.
Likewise, do not assume an older Infinity model and a current Structure share the same fit. Different uppers, sole shapes and foam arrangements can change the experience. Bring the old pair to a fitting and explain the exact feature you want to retain: heel hold, toe space, arch contact or transition.
Read the edition and width before checkout
Check the complete model name on the retailer’s listing, the size system and the actual width offered. A photo of Structure does not identify its generation, and a previous purchase in another Nike franchise does not guarantee an identical fit. Sale colors may have fewer size choices than the main product page.
Treat this as a map of Nike’s support range, not a ranked test. For a purchase decision, shortlist the model that matches your cushioning preference, confirm return conditions and compare it with your current comfortable shoe. If the arch shape is immediately intrusive, a different brand may offer a more suitable support geometry.

Is Structure 26 still worth comparing with Structure Plus?
Yes. They use different cushioning packages, so compare their fit and ride rather than assuming the Plus label makes the decision.
Does every stable-feeling Nike count as a stability shoe?
No. Personal steadiness and a manufacturer’s support category describe different things. A neutral shoe may work well without the Structure family’s deliberate guidance.
