  • Nike gives the 20th iteration of the Structure 20 a thorough makeover from the ground up. For the first time, the series uses a water-repellent DWR upper and a water resistant cleatie. Running in slight drizzle or landing on small puddles should no longer be an issue with this latest development.
  • Another very visible change in this version is the removable of most of the Flywire cables. There are now only 2 Flywire cords on both sides of the shoe that are now connected to the first two eyelets. It helps save weight with still great midfoot hold. The rest of the laces go through traditional eyelets.
  • Nike also uses an upper with bigger holes in the mesh for improved breathability. Support around the eyelets are a bit thicker for more durability as well.
  • What is most evident midsole change is the removal of the rib cage on the medial side. Nike uses a denser foam in its place to continue providing stability while enhancing the smoothness of the transitions from landing to take off.
  • Traction gets a boost with the expansion of the lugs. The lugs now extend all the way to the heel on the inner side of the shoe. With a significant increase in the number of lugs, the grip automatically improves.
  • The flex grooves in the forefoot have been removed. To maintain some semblance of flexibility, the hexagonal lugs in the forefoot are extremely well articulated.

Loyal fans of the Structure line should be happy that Nike brings back the standard fit in the Structure 20 Shield. The water-repellent version of the Structure 20 offers great hold in the heel with a decent midfoot security. Runners with flat feet will find the roomy toe box very much to their liking. There is also enough volume in the toe box for those who need extra height in the forefoot. It runs true to size.


The outsole is filled with hexagonal spanning the entire length of the shoe for enhanced grip. On the lateral side, crash rails improve the transition through the gait cycle and help stabilize the ride. Nike uses the popular BRS 1000 rubber in the Structure 20 Shield for its excellent durability. An Environmentally Preferred Rubber in the forefoot is utilized for better traction.


Nike uses two main midsole foams in the heart of the Zoom Structure 20 Shield. In what it proprietarily calls the Dynamic Support System, Nike uses both Phylon and Cushlon foams to get the balance of stability and cushioning. On the medial side is the denser foam that curbs the inward motion of the feet. The foam on the lateral side is a bit softer for cushioning. An Air Zoom unit in the forefoot adds responsive cushioning.


The H2O Repel mesh is water-repellent and quite breathable. A very plush and fine mesh is designed as an inner sleeve that creates an upper that hugs the foot in comfort and prevents the cables from digging into the foot. An Ortholite sockliner adds more comfort, support, and cushioning. The patented Flywire cables lock down the foot together with the integrated heel counter.
