adidas adizero Aegis 2 Product Review

Short Take

The adidas adizero Aegis 2 packs a bit of support into a performance trainer that, thanks to its responsive ride and snug fit, is suitable for daily training and tempo runs.

Big Features

  • Springy Midsole: The firm midsole snaps back into shape with every step, giving the shoe a sense of liveliness.
  • No Medial Post: Support is supplied through the addition of midsole material below the arch; there is no denser foam post inhibiting a smooth ride.
  • Elongated Opening: The short tongue and lower collar allow for a full range of foot movement without anything getting in the way.

Road Test

The Aegis 2 is a performance trainer with just a bit of pronation support. As with other offerings in adidas’ adizero lineup, the Aegis 2 has a highly snappy midsole for a quick toe off and a fast feel. Though not the most lightweight option at 9.5oz, the shoe feels quick and nimble - more than ready to handle fast running.

The Aegis 2 fits on the narrow side, keeping the foot snug from the toebox through the heel. Interestingly, the opening of the shoe is longer than what we normally encounter; however, we did not find this to lead to a loose or insecure fit. Some testers felt the lack of overlays towards the base of the laces made the shoe feel slightly disconnected from the foot, though this was not seen as a deal breaker.

The midsole features a pronounced decoupled heel designed to absorb initial impact, prolonging shock absorption through the heel to midfoot transition for a smoother ride. Testers were split on whether they felt the effect of the feature. Some did feel, however, that it sapped a bit of energy from the ride of the shoe. We’d like to see a lower and lighter platform in the next update of the Aegis, particularly in the heel, but this latest shoe still provides performance, a smooth ride and plenty of go-fast capability.

Runners Say


With its snappy and responsive midsole, the Aegis 2 runs like a shoe much lighter than it is.


The mesh upper is much more closed than in many other shoes. As a result the upper felt less breathable and better for cooler days.


The mild support is good for slight overpronators or for neutral runners who need support over longer runs.
