Updates to Nike Air Zoom Structure 20

  • The very popular stability shoe from Nike gets considerable modifications in the 20th edition of the Structure. One clear change is the number of Flywire cords. From 5, there are now only 2 cables that are directly connected to the first two eyelets. Midfoot hold is about the same, but the tension is now focused almost entirely on near the tip of the tongue. The well-cushioned tongue prevents any type of irritation or hot spots. The lesser number of cords saves weight and gives the upper a more refined look.
  • The Flymesh also uses bigger forefoot holes for improved breathability. Nike boosts the endurance of the upper with a thicker lamination as eyelet support. In this version of the Flymesh, there is an improved mix of structure and flexibility in areas where the runner needs it.
  • Nike wanted a ride that is a bit smoother in the Structure 20 by removing the bump in the arch. While the medial post is still around, the now almost plain arch section moves heel strike to take-off a bit quicker.
  • Stability, though, is a touch better in this version as the tri-midsole foam is a hint firmer than the earlier model. The firmer ride also makes the shoe a hair more responsive.
  • In the outsole, the lugs in the forefoot are now extended all the way to the medial part of the heel. Traction gets better with the expansion of the lugs to this area.

Nike Air Zoom Structure 20 size and fit

Nike continues to give the Air Zoom Structure 20 a very standard fit. The inner heel counter and the Flywire cables provide excellent, but not restraining hold in these areas. The forefoot has good volume and enough width for the toes to naturally splay out. As the shoe also comes in wide and extra wide versions, it should be good options for those who require extra space from the heel to the forefoot. It runs true to size.


The 20th instalment of the Zoom Structure continues to use the honeycomb outsole layout that now covers the shoe all the way to the heel on the inner side. A crash rail that extends from the heel to the forefoot gives the shoe better and smoother transitions. Two types of rubber deliver a nice blend of traction and durability. A soft blown rubber offers grip while the hard carbon rubber in the heel and midfoot provides long-lasting work.


The midsole of the Air Zoom Structure 20 is made up of a three-density foam. An injection molded EVA occupies a large portion of the midsole for main cushioning duties. On the medial side is another layer of dense foam for better support. And finally, the third wedge of foam running from the heel to the midfoot provides even more support to a collapsing arch. This midsole layout is what Nike calls the Dynamic Support System. It gives the shoe a stable ride for moderate overpronators.


Nike brings back the Flymesh upper in the Structure 20. It gives excellent ventilation and support and allows Nike to completely do away with overlays as the Flymesh itself gives enough structure and integrity to the upper. There are Flywire cables on both sides that are connected to the laces and the midsole for improved security and midfoot hold. An inner heel counter helps lock down the foot from extra movements. Nike packs the tongue with enough foam to prevent the cords from causing irritation. A removable sockliner adds cushioning, support, and a little responsiveness to the shoe.
