adidas Adizero Boston 12 - Black - 8.5

These shoes are best suited for speed workouts, tempo runs, long training runs, and as a versatile shoe for race day preparation. They excel in scenarios where performance and efficiency are key.

Gently clean the shoes with a soft brush or cloth, mild soap, and cold water. Avoid machine washing or using harsh chemicals. Always air dry them away from direct heat.

While you can wear them casually, the Adizero Boston 12 is highly optimized for performance running. Its features are designed to enhance training and racing, which may make them feel firmer or less plush than dedicated casual sneakers.

The Adizero Boston 12 features ENERGYRODS for tuned stiffness. Allow for a short break-in period of a few runs. If discomfort persists, ensure the lacing is not too tight and consider your running form or foot mechanics.

Ensure laces are tied securely, potentially using a runner's knot for better heel lock. Check that you are wearing appropriate running socks and that the shoe size is correct for your foot length and width.

Running shoes have a finite lifespan. If you've accumulated significant mileage (typically 300-500 miles, varying by runner), the cushioning may be packed out. It might be time to consider replacing your shoes.
