Updates to Adidas Adizero Prime

  • The Adidas Adizero Prime is a 2019 update to a relatively well-known product that bears the same name. The façade follows the structure of the prior iteration: a slip-on Primeknit silhouette that’s merely supported by the discreet lacing system. But the difference lies in the design of the fabric; while the previous one sported a smooth structure that had open-weave sections, the 2019 Adizero Prime employs a ridged cover system that assisted in improving snugness.
  • The midsole unit is composed of a two-layer cushioning system. The first one is a foam topsole that is responsible for being the platform on which the foot can rest; the bottom layer is boost™, a highly-regarded technology made of amalgamated thermoplastic polyurethane pellets.
  • Protection against the abrasive nature of the surfaces is the job of the Continental™ rubber outsole. This layer is also responsible for doling out traction, a trait of a shoe that is essential for precise movements.

Size and fit

The Adidas Adizero Prime was constructed to be true to size. Runners are welcome to purchase a pair with their using sizing expectations in mind. Full and half sizes are the available variants for this model. The unisex configuration would mean that women who want to try on this shoe should go down one or one-and-a-half sizes to achieve the desired in-shoe fit. When it comes to width, the choice is D – Medium.

This road running shoe has a semi-curved shape and a stretchy upper that welcomes the natural outline of the human foot.


The outsole unit of the Adizero Prime is made of Continental™ rubber, a compound that’s typically used in car tires. The purpose of this layer is to protect the midsole from wear-and-tear, thus maintaining its efficacy and form. It also makes sure to provide grip for precise movement control over dry and wet surfaces.

Shallow flex grooves line the outsole horizontally. These superficial trenches allow the platform to bend in conjunction with the foot as it takes each step. The phase in the gait cycle that benefits the most from such a feature is the toe-off, the part that involves the most foot flexibility.


A foam topsole serves as the platform on which the foot can rest. This layer has a soft yet steady construction which allows the foot to maintain a fixed position inside the shoe. Its movement-friendly structure doesn’t hinder the flexibility of the rest of the platform.

The base of the Adidas Adizero Prime’s sole unit is comprised of boost™, a cushioned piece made of fused-together thermoplastic polyurethane (TPU) pellets. The job of this technology is to attenuate the impact shock generated by the landing phase of the gait cycle, then returning the energy to the foot for an invigorating toe-off. Many flagship products use this feature, including the ever-popular Adidas Ultra Boost.

The Torsion® System is a plastic cage between the midsole and outsole. The job of this part is to support the arch, preventing it from flexing incorrectly during the run. It also prevents the platform from breaking down or sagging quickly.

An insole is placed right above the primary cushioning system of this neutral running shoe. This add-on adds a bit more oomph to the underfoot experience. It can be detached or replaced with a different one if the runner chooses to do so.


Primeknit serves the primary cover system of the Adidas Adizero Prime. This feature has a cloth-like quality to it that allows it to stretch and mold itself to the shape of the foot that it surrounds. It has a ribbed exterior to help in securing the foot and locking it in place.

The seamless construction of the façade prevents hot spots or other sources of chafing. Such a build allows runners to wear this running shoe without putting on socks first.

The Microfit is a cover system that’s mainly made for Adizero shoes. It entails a form-hugging structure of the upper that precisely mimics the outline of a forward-propelling foot.

A one-piece opening allows runners to slip the foot into the interior chamber without adjusting a traditional tongue unit. The all-encompassing nature of the collar locks the foot down and prevents road debris from sneaking into the shoe’s sleeve.

Subtle padding graces the interior of the silhouette. It lightly cushions the ankles and Achilles tendon, shielding them from the impact forces and other vibrations.

An adaptive lacing system snakes across the instep of the Adidas Adizero Prime. It involves flat laces that go through print-reinforced eyelets. The crisscrossing strands can be tightened or loosened to follow the fit preferences of the wearer. Multiple extra apertures are placed near the collar to allow for extra heel security.
