This was my first time running in the Structure, and I appreciate how light they felt on my feet. I typically run 3–5 miles daily on a treadmill, and the shoe delivered a secure, locked-in feel with every stride. However, as my feet began to swell during longer runs, the fit started to feel a bit tight and restrictive. The upper is thick and snug, which helped with stability, but I found myself wishing for a bit more breathability. I’ll likely go up half a size next time to improve comfort on extended runs.

My lower arches appreciate the wider midfoot and the updated react x foam is great, but the tongue design is horrible. The Structure 26 would be better with at least a semi-gusseted tongue like on the Pegasus 41. Also an 8mm drop as featured on the Structure 23/24 would be great. Please get rid of the unneeded tongue pull tab, a nice semi-gusseted would solve that. Thanks for trying. A little better than the Structure 25.Hopefully the Structure 27 will fix the tongue issue. Thank you.

this shoe only look good, but the fit is something not that good
