Adidas Adizero Boston 12

The Adidas Boston 12 arrive as an interesting proposal in the running world. At first glance, they stand out for their stylish design and promise to be a versatile tool for different types of training.

First impressions when wearing the Adidas Adizero Boston 12

When I put on these shoes for the first time, I notice a feeling of firmness combined with a surprising lightness. The fit is snug but comfortable, although the heel area requires a bit of attention to ensure proper lockdown. The lacing system offers enough flexibility to adjust pressure, but may require some experimentation to find the perfect balance.

Running Feel

Once on the move, the Boston 12 feels nimble and responsive. The transition from heel to forefoot is smooth, thanks to the lateral heel tilt and Energy Rods arrangement. The midsole, combining Lightstrike Pro and Lightstrike EVA, offers a balanced blend of cushioning and energy return, which translates into efficient momentum in every stride.

Performance at different paces

These shoes shine at a wide range of paces. For slow and steady workouts, they provide the cushioning needed without sacrificing ground feel. At faster paces, such as series or tempo workouts, the firmness and responsiveness become more evident, offering that sense of speed and efficiency that many runners are looking for.

Recommendation for runner types

The Boston 12 is ideal for neutral runners looking for a versatile shoe for varied workouts. Given their combination of cushioning and responsiveness, they are especially recommended for those looking for a shoe for long distances or speed sessions. However, runners with a very pronounced heel strike or those who prefer a looser fit may need to consider other options.

Durability and quality materials

When it comes to durability, Adidas does not disappoint. The Continental rubber outsole ensures a long lifespan, even under intense training conditions. The upper, while lightweight and breathable, seems sturdy and well-built, promising to withstand miles of wear and tear.

What I liked most

• Versatility in performance: The Boston 12 shines for its ability to adapt to different types of workouts. From long runs to speed sessions, they respond exceptionally well, making them a very versatile option.
• Combination of cushioning and responsiveness: The midsole, with its blend of Lightstrike Pro and Lightstrike EVA, provides comfortable cushioning without sacrificing responsiveness. This translates into an efficient and enjoyable run, especially at varied paces.
• Quality materials and durability: Durability is a strong point, with a Continental rubber outsole that promises long-lasting performance and a tough upper that stands up to regular training wear and tear.
• An all-around shoe: Despite good cushioning, the shoes maintain excellent ground feel, allowing for a clear and direct feel that promotes agility and quick response.

What I liked least

• Heel fit and lacing system: The fit in the heel area could be somewhat more plush and comfortable, requiring special attention to achieve proper lockdown. Also, the lacing system may need frequent adjustments to find the perfect balance between comfort and security.
• Initial stiffness: At first, the shoes may feel somewhat stiff, requiring an adjustment period. This could be a drawback for runners who prefer an immediate feeling of flexibility and comfort.
• Feeling of excessive firmness at slow paces: While an advantage at fast paces, the firmness of the shoe may feel a bit less comfortable in slower or more relaxed workouts.

The Adidas Boston 12 presents itself as an excellent choice for runners who value versatility and efficiency. While their fit may require some adjustment, once sorted out, they offer an enviable running experience. They are a solid choice for both daily workouts and more demanding sessions, honor to their reputation as one of the most versatile shoes on the market.

The adidas Adizero Boston 12 stands as a true icon in the realm of running shoes, a testament to its enduring presence in races ranging from 10Ks to marathons. Well, after more than 3 months running with these shoes, I think I have discovered the reason for their popularity.

First impressions: Versatility in their DNA

Putting on the adidas Boston 12 for the first time, its reputation for versatility becomes immediately apparent. This shoe effortlessly adapts to various running conditions. Although its foam feels softer than its predecessor, the Boston 11, it retains a distinctive firmness that sets it apart.

Pace and distance

The Boston 12 excels with pace variation. At slower speeds, its stiffness is noticeable, but as you pick up the pace, the shoe reveals its true capabilities. The inclusion of Lightstrike Pro foam, in tandem with energy rods, provides a stiffness akin to a carbon plate, offering additional propulsion during intense workouts.

Ideal runner type: Training and racing focused

Designed with performance-oriented runners in mind, the Boston 12 is ideal for those looking to enhance their racing and training outcomes. It caters to experienced runners who are not quite ready to transition to more advanced models like the Adios Pro 3 but seek a capable intermediate option from adidas.

Possible areas for improvement

If there's one thing about the Boston 12 that left us wanting more, it's the upper. The mesh material employed by adidas feels stiff in certain areas, and the lack of structured support around the collar could pose issues for runners requiring more stability, particularly on trails or sharp turns. Despite its lightweight and minimalist design, there's room for improvement in terms of fit and comfort.

The Adidas Boston 12 is a mixed shoe that shines in quality workouts. For slow paces there are more comfortable options, but in fast sets or intervals, this shoe responds exceptionally well. Its sweet spot is in the forefoot, ideal for midfoot runners.

Alternatives to the adidas Boston 12

Compared to alternatives like the New Balance SC Trainer v2 or the Hoka Mach X, the Boston 12 may not be the most comfortable in the upper, but it outperforms in reactivity thanks to its combination of foams and energy rods. Its outsole, bordering on excellence, offers formidable grip on the road, although on more uneven surfaces, you may not feel as confident.

Bottom line: A great choice for the all-around runner.

All in all, the adidas Adizero Boston 12 is a formidable all-purpose option. Ideal for training at varied paces and competitions where reactivity is key. While it may not be the best choice for those looking for paces under 3'30"/km, for the rest, the Boston 12 is a safe bet. With the Boston on your feet, every race becomes an opportunity to excel.
