Design changes in the adidas Adizero Boston 12 mark a bit of a departure in this saga. Traditionally, the previous versions of the Adidas Adizero Boston stood out as versatile, lightweight shoes suitable for sprints, daily workouts. The transformation of the Adizero Boston 12 into a speed trainer with a focus on durability might disappoint those who were looking for the versatility of previous models. Perhaps it's a very personal opinion from RUNNEA but we feel that the essence of what this mixed shoe from adidas stood for has been lost a bit.

In the Adidas Adizero Prime X 2 Strung we put the focus on the upper and its weight. Its upper cut doesn't fit as loose compared to previous models, and its weight increase over the previous version may be an aspect to consider.

Final conclusions of the adidas comparison.

The adidas Adizero Prime X 2 Strung feature noticeable improvements, such as a wider base and softer forefoot, which contributes to a more comfortable running experience. However, there are also areas of improvement, such as a slightly looser upper, increased weight and a thinner rubber outsole. Overall, this second version represents a considerable improvement over its predecessor, as it has become more user-friendly and focused on stability. This allows runners to enjoy smoother runs without worrying as much about landings. In addition, its increased stability makes it suitable for a wider variety of runners.

On the other hand, the adidas Adizero Boston 12 is a solid upgrade for those looking for a durable and firm shoe with effective cushioning. They are ideal for runners who want a lighter and faster alternative compared to Solar Boost or Solarglide.

In summary, both the Adidas Adizero Prime X 2 Strung and the Adidas Adizero Boston 12 offer exciting options for runners with diverse needs and preferences. The comfort and stability improvements of the Prime X 2 Strung make it a fun and versatile choice for runners looking for outstanding performance, while the Boston 12 is a solid choice for those who value durability and firmness in their runs.
