FAQs

What type of running is the Adizero Boston 12 best for?

These shoes are specifically designed for mid- to long-distance running, particularly for tempo training runs where you want a fast and propulsive feel.

How much does the Adizero Boston 12 weigh?

The shoe weighs approximately 219 grams (7.7 oz) for a size 40 (EU) / UK 6.5 (men's).

What is the heel-to-toe drop of these shoes?

The Adizero Boston 12 has a 7 mm drop, with a heel stack height of 38 mm and a forefoot stack height of 31 mm.

Are these shoes suitable for wet weather conditions?

Yes, the Continental™ Rubber outsole provides excellent grip and traction on both dry and wet road surfaces, with up to 30% improved grip on wet conditions.

Do these shoes use recycled materials?

Yes, the upper part of the shoe is made with a minimum of 50% recycled content, contributing to adidas' efforts to reduce plastic waste.

What kind of cushioning technology is used?

The shoes feature a dual-layer cushioning system with ultra-light Lightstrike Pro for maximum energy return and Lightstrike 2.0 EVA for enhanced softness, lightness, and durability.

Is there a recommended runner weight for these shoes?

Yes, the Adizero Boston 12 is generally recommended for runners weighing less than 85 kg to optimize performance and cushioning benefits.

How do the ENERGYRODS 2.0 improve performance?

The glass-fibre infused ENERGYRODS 2.0 are strategically placed in the midsole to limit energy loss and create a propulsive sensation, allowing for more natural and efficient transitions during your run.

Troubleshooting

Feet feel hot or sweaty during runs.

The Engineered Mesh upper is designed for breathability. Ensure you are wearing appropriate moisture-wicking socks. If the issue persists, check that your shoes are not tied too tightly, restricting airflow.

Lack of expected propulsion or 'bounce'.

Ensure your running form utilizes the midfoot strike to engage the ENERGYRODS 2.0 and Lightstrike Pro cushioning effectively. For optimal performance, these shoes are best suited for tempo runs and mid- to long-distance efforts where their propulsive elements can truly shine.

Shoes feel slippery on wet surfaces.

The Continental™ Rubber outsole offers enhanced grip on wet surfaces. While it significantly improves traction, no shoe can entirely eliminate slippage on all wet or extremely slick surfaces. Adjust your stride and pace in very wet conditions.

Discomfort or pain, especially for heavier runners.

These shoes are recommended for runners under 85 kg. If you are above this weight, the cushioning and support might not provide optimal protection or comfort, potentially leading to discomfort. Consider shoes designed for heavier runners or those with more inherent stability.

Shoes feel too stiff or unnatural.

The ENERGYRODS 2.0 provide a structured, propulsive feel that might take a few runs to get accustomed to if you're used to very flexible shoes. Give them a few runs to break in and allow your foot to adapt to the dynamic ride.

Pros and Cons

Setup, Compatibility & Care

Setup

The Adizero Boston 12 features a standard lacing system. Simply lace them up as you would any traditional running shoe, ensuring a snug but comfortable fit. The engineered mesh upper is designed to adapt to your foot for immediate comfort, minimizing the need for an extensive break-in period.

Compatibility

  • Running Surface: Optimized for road running (`Route`).
  • Stability: Offers neutral stability, making it suitable for runners with a neutral gait.
  • Drop: Features a 7 mm drop (38 mm heel / 31 mm forefoot), which is a common preference for many runners.
  • Footwear Size: This specific variant is UK 7.5 (adult male).

Care

Proper care will extend the life and performance of your Adizero Boston 12 shoes:

  1. Cleaning: After runs, especially in dirty or muddy conditions, gently brush off loose dirt. For deeper cleaning, use a mild soap and cold water with a soft brush or cloth. Avoid harsh chemicals or machine washing, as this can damage the materials and adhesives.
  2. Drying: Always air dry your shoes at room temperature. Do not expose them to direct heat sources like radiators or direct sunlight, as this can cause materials to shrink, crack, or degrade.
  3. Storage: Store your shoes in a cool, dry place away from direct sunlight. Remove insoles after particularly sweaty runs to allow them to air out separately, preventing odor buildup.
  4. Rotation: If you run frequently, consider rotating your Adizero Boston 12 with other running shoes. This allows the cushioning and materials to decompress and recover, prolonging their effectiveness.
