adidas’ famous Boost technology was developed for better cushioning in running shoes, before consumers started wearing them for everyday purposes. Now, adidas is releasing the next evolution to the world in the form of the adidas Adizero Sub2.

adidas first debuted the Boost midsole technology in 2013, which took off to great success in 2015. This year, the Three Stripes is celebrating the five year anniversary of the revolutionary foam beads, including the public introduction of Boost Light. Billed as the next evolution of Boost, the new Light format promises to reduce the weight of the foam while retaining the same bouncy responsiveness. adidas did not offer any explanation as to how this is achieved, so it will certainly be interesting to compare the new and old versions because Boost is already one of the lightest midsole technologies on the market. With a worldwide retail rollout on the way, it can be assumed that adidas is manufacturing Boost Light on a large scale, meaning another migration into the lifestyle category could happen soon.

The next evolution of Boost was first introduced in the form of the adidas Adizero Sub2. Worn by Wilson Kipsang, the shoe was designed specifically for him in an effort to break the two hour marathon barrier, a seemingly impossible feat. Kipsang debuted the shoe last year at the Tokyo Marathon, running an incredible 2:03:58 marathon, his second fastest ever. This year, he’ll return to Tokyo to attempt the record again, this time in a new colorway of the Adizero Sub2 that will release to the public next month.

The lifestyleThe adidas Adizero Sub2 is a very simple and slim silhouette, built to be incredibly light but durable enough for a marathon. The full-length Boost Light midsole is said to be the lightest ever from adidas, and is given a grey and white marble look to simulate clouds under your feet. The lighter foam is protected from wear by a new Continental Microweb outsole, an evolution of the signature Stretchweb that was developed specifically for Boost technology. The upper is a single-piece construction made from an ultra-light mesh, which features new Microfit technology to provide better support and comfort for athletes. The first iteration will feature an all black upper with white stripes and Adizero branding. The model was pre-released in extremely limited fashion to elite runners at the Berlin Marathon Expo in September 2017 for $180, and will receive a worldwide release next month.


The adidas Adizero Sub2 will be available from adidas and and their retail partners worldwide on March 15th, 2018, for a price of $180.
