FAQs
What type of running is the adidas adizero Boston 12 best suited for?
The adizero Boston 12 is best suited for speed work, tempo runs, interval training, and race day efforts for distances from 5k to marathon. Its design prioritizes propulsion and efficiency.
What is the heel drop of this shoe?
The adidas adizero Boston 12 has a heel drop of 7mm.
What is the weight of the adizero Boston 12?
The shoe weighs 267g (9.4 oz).
How do the EnergyRods 2.0 work?
The EnergyRods 2.0 are designed to mimic the metatarsal bones of the foot. When embedded in the midsole, they provide stiffness and leverage, working with the foam to reduce energy loss and create a propulsive, efficient ride that helps transfer power forward.
Can I use the Boston 12 for daily training?
While durable enough for regular use, the Boston 12 is optimized for faster-paced training and racing. For slow, easy daily runs, you might prefer a shoe with more traditional cushioning. It excels as part of a shoe rotation.
What is the stack height of the shoe?
The stack height of the adidas adizero Boston 12 is 38mm in the heel and 31mm in the forefoot.
Is the Continental rubber outsole good for wet conditions?
Yes, the Continental rubber outsole is known for providing reliable grip and traction in various conditions, including both wet and dry surfaces, ensuring confidence during your runs.
Troubleshooting
My heel feels like it's slipping.
Re-lace your shoes, ensuring the laces are snug but not overtightened, and consider using a 'runner's knot' (heel lock lacing) for enhanced lockdown at the ankle. The Slinglaunch heel system should naturally provide good security, so ensure proper lacing technique.
The ride feels too firm or unresponsive.
While the Boston 12 is designed for responsiveness, ensure you've given them a few runs to break in. The foams may soften slightly over initial uses. Also, ensure the shoes are being used for their intended purpose – speed work and tempo runs – where their propulsive qualities are most apparent. They might feel firmer during slow, easy efforts.
I'm experiencing discomfort in the arch or forefoot.
Check if you have the correct size. Too small can cause pressure, too large can cause rubbing. Also, try different socks; thin or thick socks can alter fit. If discomfort persists, consider if your foot shape is compatible with the shoe's last, or consult with a running specialist for insole recommendations.
Pros and Cons
Pros
- Enhanced power transfer and propulsion for faster running.
- Responsive and well-cushioned ride suitable for tempo and speed work.
- Secure and comfortable fit, especially around the heel.
- Excellent grip on various surfaces thanks to Continental rubber.
- Lightweight design contributes to a feeling of speed and agility.
- Promotes a smooth and efficient heel-to-toe transition.
Cons
- May feel firmer than dedicated plush trainers for recovery runs.
- The specific feel of the EnergyRods might not suit all preferences.
- Info needed: Durability for very high mileage daily training might be less than traditional trainers.

Setup, Compatibility & Care
Setup
Using your adizero Boston 12 shoes is straightforward. Simply put them on and adjust the lacing to achieve a snug, comfortable fit. Ensure your heel feels securely cradled by the Slinglaunch system without excessive pressure on your Achilles tendon. Experiment with different lacing techniques if you have specific fit preferences, such as a runner's knot for extra heel lockdown.
Compatibility
These shoes are designed for male runners who prioritize speed, responsiveness, and efficiency. They are compatible with a variety of foot strikes thanks to the adaptive Continental rubber outsole. Ideal for structured training sessions like tempo runs, interval training, and longer race simulations, they complement a rotation that might also include a dedicated recovery shoe.
Care
Proper care extends the lifespan and performance of your running shoes:
- Cleaning: Gently brush off loose dirt with a soft brush (e.g., an old toothbrush). For tougher spots, use a mild soap and cold water with a soft cloth. Avoid harsh detergents or machine washing, as this can damage materials and adhesives.
- Drying: Allow shoes to air dry naturally at room temperature. Do not put them in a dryer or expose them to direct heat sources like radiators, as this can warp materials.
- Storage: Store your shoes in a cool, dry place away from direct sunlight. Avoid leaving them in a hot car, which can degrade foams and adhesives.
- Rotation: If you run frequently, consider rotating your Boston 12 with another pair of shoes. This allows the foam to decompress and recover between runs, potentially extending its lifespan and consistent performance.
