adidas Adizero Boston 12 - Silver Metallic Pulse Lime - UK 11

These shoes are best suited for mid- to long-distance training, including tempo runs, long runs, and faster-paced workouts. They are designed to provide a race-day feel for regular training.

The ENERGYRODS 2.0 are glass-fibre infused rods integrated into the midsole. They are designed to mirror the metatarsals of the foot, limiting energy loss and providing a stiff, propulsive feeling that helps drive you forward more efficiently.

Lightstrike Pro is an ultra-light and highly responsive foam that offers excellent energy return. Lightstrike 2.0 EVA is a newer, more durable version of Lightstrike foam, providing robust cushioning and longevity, complementing the Lightstrike Pro for a balanced, durable, and energetic ride.

While they offer a 'race-day feel,' the Adizero Boston 12 is specifically designed as a versatile training shoe for daily runs, particularly for mid- to long distances and speed work. They are built with durability in mind for regular use.

Use a soft brush to remove loose dirt. For stains, use a mild soap and lukewarm water solution with a cloth or soft brush. Avoid machine washing or using harsh chemicals. Always air dry them at room temperature, away from direct heat or sunlight.

The lifespan of running shoes varies based on individual running style, body weight, and mileage. With the inclusion of durable Lightstrike 2.0 EVA, these shoes are built to last. Generally, performance training shoes like the Boston 12 can offer optimal performance for approximately 300-500 miles.

While the Boston 12 can handle speed work due to its propulsive nature, it is optimized for mid- to long-distance efforts. For very short, high-intensity track workouts, some runners might prefer even lighter, more minimal track spikes or dedicated racing flats, but the Boston 12 will perform well.

The engineered mesh upper is designed for breathability. Ensure you are wearing appropriate running socks made of moisture-wicking materials. Avoid cotton socks, which retain moisture. Also, check that your shoes aren't laced too tightly.

Performance shoes, especially those with energy rods, can sometimes feel stiff out of the box. Allow for a short break-in period of a few shorter runs (e.g., 2-3 runs of 3-5 miles) to let the materials conform to your foot and soften slightly. Ensure your lacing isn't too tight, which can restrict foot movement.

Try using a 'runner's knot' or 'heel lock' lacing technique. This involves using the extra eyelets near the ankle to create a loop that pulls the shoe more securely around your heel, preventing movement without overtightening the forefoot.

Running shoe midsoles, especially performance foams, will eventually compress and lose their responsiveness. While the Lightstrike 2.0 EVA adds durability, regular usage will still lead to wear. Track your mileage; most performance training shoes last between 300-500 miles depending on running style and body weight. Consider if it's time for a new pair.

Squeaking can sometimes be caused by moisture trapped between the insole and the strobel board, or by debris in the outsole. Try removing the insoles and letting both the shoes and insoles air dry completely. If the squeaking persists, check the outsole for any embedded small stones or foreign objects.
