NIKE Men's Air Zoom Structure 21 Running Shoes

Product Information

In case if you found the last year’s Structure 20’s ride to be hard on your feet, consider the list of alternatives at the end of this review. PROS AND CONS

The excessive outwards bias or lean of the older Structures (17, 19) is no longer present on the 21. The rearfoot has a bit of an outer bias due to the midsole groove and the beveled heel, but only slightly so. The laces are now flat instead of round. These flat laces pass better through the strap-based cinching system. The Structure 21 uses a strapping system (or the internal ‘arch-band’ in Nike-speak) which was also used on the 20. The rest of the upper fits beautifully. The midfoot fit is far superior to the Flywire-based cinching of the Structure 18 and 19. Overall, the Nike Zoom Structure 20 and 21 are responsive, well-cushioned and deliver an energised ride with smooth transitions. They are engineered to meet the needs of overpronating runners with plenty of midsole foam cushioning to keep wearers stable and support the collapsing arch. Additionally, both models also accommodate users with broader feet by offering wider width sizes for buyers.Two shoes from New Balance complement the Structure 21 perfectly. The first is the newly released 1260V7 – a cushioned stability model. The second shoe is the 1500V3, one of our favorite road racers which combine lightweight cushioning with mild support. SIMILAR MID-PRICED SUPPORT SHOES When I walked around in the Structure 25 for the first time, it was noticeable how much more it felt like a stability trainer than the last 2 versions. There was a prominent arch sensation which wasn’t there since the Structure 19 but it wasn’t painful or uncomfortable. For reasons best known to Nike, the Zoom Structure has rarely had a plushly padded tongue or heel lining. Thankfully, the Structure 20’s tongue quilting is nowhere as bad as the Structure 18. My podiatrist informed me that one’s preference in drop height of a shoe relates to one’s Achilles flexibility—but no two people are alike in terms of an exact “if this then that” diagnosis: you’ll have to try out a few different types to see what really works for you. Nike Zoom Structure 21 General Info

The ride quality hasn’t changed at all, so the upper gets all the new updates. That being said, all changes are design and material related. Little has changed in how the Structure fits. Ventilation is improved on the 21 due to the new fabric, and the optional widths help you choose the kind of fit you want.

The Nike Zoom Span 2 is much nimbler shoe than the Structure while being cheaper and lighter. The midsole has a hint of support, and the upper feels fast trainer like. It is one of Nike’s most under-rated shoes which also happens to be great value for money. RECOMMENDED ROTATION There are other subtle changes, all of them for the better. The upper has larger vented areas. The forefoot breathes better, and so does the rearfoot which now gets vented sections over the Flywire cords. Given the overall firm nature of the midsole, the ride is fairly supportive. Unlike some of the older Structure (17, 19) models, the 21 has minimal ride bias towards the outer side. SUMMARY, AND CHANGES BETWEEN THE STRUCTURE 20 AND STRUCTURE 21 The Nike Air Zoom Structure 22 is a running shoe designed for people with flat feet. It helps runners to train with appropriate support. Plantar fasciitis or flat feet problems can be treated by regular stretching but wearing a shoe that supports the arch and heel correctly is a more lasting solution and that's where the Zoom Structure 22 comes in. The product is also a good choice for anyone who trains daily with a view to covering longer distances as it its hard-wearing and offers good support over an extended period of time.
