This lightweight shoe is designed for fast runners and people who like to run a lot of miles. Specifically, it is a minimal shoe created for racing, daily training, and speedwork. It is a motion control trainer that gives much needed support for mild to moderate over-pronation. The Adidas Adizero Aegis 2 is the second iteration of this particular Adidas shoe and the reviews from runners and testers are mixed. But first, a little bit about the shoes features.
Cushioning: The EVA based foam, adiPRENE, is used in the forefoot to cushion the metatarsal area. Adidas uses Formotion gender specific decoupled heels to absorb and disperse the energy that comes from the heel landing. The midsole features compression molded EVA that also enhances durability and cushioning
Midsole: The Torsion System is a thermoplastic unit shaped like a wishbone. It runs along the bottom of the midfoot and works to improve stability by allowing the fore and rear foot to operate independently. The engineering on this system is gender specific to support men and women’s differing gait needs.
Upper: The tongue and the upper have been combined to reduce the weight as well as enhance collar comfort. The antibacterial sockliner wicks away moisture and kills odor causing bacteria while the open mesh design allows air to circulate to keep feet dry and odor free. Interestingly, the Adidas logo was incorporated into the shoe in a way that wraps the upper around the foot.
Outsole: The lateral heel consists of carbon rubber while blown rubber is used in forefoot. Both are lightweight materials that reduce abrasions and increase traction. This is great for outdoor runs during or after weather conditions that made the running surface slippery.
The Adidas Adizero Aegis 2 is thin and flexible which is perfect for a variety of training work. Cushioning is modest but provides for a plush ride. The forefront logs goes a long way towards achieving traction on slippery surfaces and the mesh keeps feet from getting overheated while on the road.
Runners and testers enjoyed its lightweight but some felt the shoe did not offer enough cushioning and felt their feet were exposed. The shoes seemed to require a break in period so they are not able to go from the box to a marathon. One reviewer did not like the shoes until they put in about 25 miles. Afterwards, the outsole and foam softened enough to provide a comfortable ride.
Another reviewer reported there was enough room in the toe box to keep wide forefeet comfortable though they found the midsole/outsole to be stiff but responsive. After a 15 mile test, the shoes appeared to hold up under the beating they gave them.
One major turn off was the cloven heel and the colors. If you run on rocky surfaces, the heel can pick up small rocks which can interfere with your run. The shoe comes in a neon green which is not everyone’s cup of tea.
Overall, the Adidas Adizero Aegis 2 fits and performs like a performance trainer. The shoes are certainly worth taking for test drive to see if these will work for your training program.
