Adidas Adizero Boston 12: A Versatile Workhorse


For runners seeking a well-cushioned, responsive trainer capable of handling everything from easy miles to uptempo workouts, the Adidas Adizero Boston 12 delivers. This latest iteration of the famous Boston line brings critical updates that improve the ride quality while maintaining the shoe's versatility.

Energized Cushioning

At the core of the Boston 12 is Adidas's Lightstrike Pro midsole foam, known for its bouncy, energetic ride. This PEBA-based compound provides excellent energy return to make your stride feel more propulsive. [1][2][3][4][5][6][7]

The midsole utilizes a generous stack of Lightstrike Pro (31mm heel, 26mm forefoot) layered over a new, softer Lightstrike 2.0 EVA foam. This dual-density setup gives you responsive cushioning up front with a touch more give in the heel for smooth transitions. [3][4][5][6][7]

Adidas's new ENERGYRODS 2.0 system is embedded within the midsole - a full-length glass fiber-infused rod that provides lightweight stiffness and propulsion. This cohesive rod design improves durability compared to previous versions. [3][4][10]

Smooth, Stable Ride

One key update to the Boston 12 is its wider midsole geometry compared to version 11. This increases the shoe's base significantly to enhance stability, especially in the heel area during footstrike. [1][2][3][4][5][10]

Adidas also tweaked the midsole shape with a more aggressive toe spring and rocker geometry. This promotes smooth, rocking transitions from footstrike to toe-off for an efficient stride. [10]

One reviewer noted, "The forefoot grip is stellar, and running fast in them just feels so right, so economical."[6]

Durable Traction

The outsole of the Boston 12 features a durable Continental rubber compound that provides excellent grip on roads and light trails. Adidas added more rubber coverage than version 11, increasing overall longevity. [1][3][5][8]

Multiple reviewers reported outstanding outsole life after 100+ miles, with one stating: "I have 160 miles in my first pair of these & the rubber in the outsole is still great & the foam has softened up very nicely btw 60-100 miles."[8]

Lightweight, Breathable Upper

The engineered mesh upper on the Boston 12 is lightweight and breathable to keep feet cool on long runs. It provides a snug, secure fit through the midfoot thanks to an internal support skeleton. [1][2][3][4][6]

Some reviewers did note the toe box felt a bit narrow and tapered, so trying them on or going up a 1/2 size can help alleviate any toe cramping on longer efforts. [5][6]

A Versatile Daily Trainer

The Adidas Adizero Boston 12 is a highly cushioned, responsive, and durable trainer suitable for everything from daily miles to uptempo workouts. Its energetic Lightstrike Pro foam, propulsive ENERGYRODS system, and stable midsole geometry make it a fantastic option for runners seeking one versatile shoe in their rotation.

While not as lightweight as some carbon racers, the Boston 12 makes up for it with impressive cushioning, a smooth ride, and longevity that could see it transition from workout companion to daily trainer as the miles add up. This propulsive shoe is worth a look for runners seeking a well-rounded workhorse.
