adidas’s Revamped Boston 12: Lighter and Simpler


The adidas Adizero Boston 12 Shoes are built for mid- to long-distance running, bringing a race-day feel to training with a propulsive feel that comes from glass-fibre infused Energyrods 2.0, which limits energy loss underfoot. They’re fast, but that does not come at the cost of durability. And now, as part of substantial changes, the midsole is made from two layers – ultra-light Lightstrike Pro cushioning and a new version of durable Lightstrike 2.0 EVA.

The Changes
The Lightstrike 2.0 is not the only change in the midsole. The whole design has changed too. In the forefoot, the Lightstrike Pro plunges deeper towards the road than before and is more substantial in the heel too. Overall the heel has dropped just over a millimetre for a slightly lower stack height.

The cushioning is also greater in the V12 as the Lightstrike 2.0 is less dense, more resilient and has extra energy return…

The cushioning is also greater in the V12 as the Lightstrike 2.0 is less dense, more resilient and has extra energy return. Overall the shoe is now 40g lighter and the changes in the upper have a lot to do with that. By discarding the suede fabric, heel counter and overlays of version 11, version 12’s upper becomes a whole lot simpler and lighter.

For Elites and You

Flexi Plan
The Adizero range is here to cater for elite runners which often means the shoe is stiffer than normal shoes. That was the case with the Adizero Boston 10 and 11. But with this new version the flex is a little snappier, which means more runners will enjoy this ride, not just the elites. 


Engineered Mesh Ready for tempo training runs with a breathable fit. Targeted support of engineered key zones provide both midfoot lockdown and forefoot flexibility.

Energy Rods 2.0 High-performance midsole stiffness made possible from the glass fibre-infused Energyrods 2.0. A holistic system designed for a seamless transition from heel to toe, bringing race-day performance to high-speed training runs.

Lightstrike Pro + Lightstrike 2.0 A layered midsole construction consisting of adidas’ high-performance foam, Lightstrike Pro and the all-new Lightstrike 2.0, is engineered to deliver a cushioned and dynamic ride. The Continental outsole provides great grip in all conditions. 

Made in Part By Recycled Materials Made with at least 50% recycled materials in the engineered mesh upper, this shoe contributes towards helping end plastic waste.
