FAQs

Are the adidas Adizero Boston 12 suitable for daily training?

Yes, while they offer a race-day feel, the Adizero Boston 12 are built with durability in mind (thanks to `Lightstrike 2.0 EVA`) making them excellent for daily mid- to long-distance training runs, tempo efforts, and even long-run days.

What is `ENERGYRODS 2.0` and how does it benefit my running?

`ENERGYRODS 2.0` are glass-fibre infused rods embedded in the midsole. They are designed to limit energy loss during your stride, providing a propulsive feel that helps you maintain speed and efficiency over long distances by returning energy with each step.

How should I clean my Adizero Boston 12 running shoes?

To clean your shoes, gently wipe them with a damp cloth and a small amount of mild soap. Avoid submerging them in water or using harsh cleaning agents. Allow them to air dry completely at room temperature, away from direct heat or sunlight.

What is the midsole drop of these shoes?

The Adizero Boston 12 has a midsole drop of 7 mm, with a heel height of 38 mm and a forefoot height of 31 mm. This drop is a common preference for many runners, offering a balanced feel.

Are these shoes environmentally friendly?

The upper of the Adizero Boston 12 contains at least 50% recycled materials, contributing to adidas' efforts to reduce waste and environmental impact.

What type of runner would most benefit from the Adizero Boston 12?

These shoes are best suited for mid- to long-distance runners who prioritize speed and efficiency in their training. They cater to those looking for a propulsive, lightweight, yet durable shoe for tempo runs, long runs, and preparing for races like marathons.

Troubleshooting

My feet feel hot or sweaty during runs.

Ensure you are wearing appropriate moisture-wicking running socks. The lightweight mesh upper is designed for breathability, but proper sock choice can further enhance comfort. If the issue persists, consider airing out the shoes immediately after each run.

The shoes feel too stiff or uncomfortable initially.

Running shoes, especially those with advanced propulsion systems like `ENERGYRODS 2.0`, often require a break-in period. Wear them for shorter runs or walks before tackling longer distances. This allows the materials to conform to your foot shape.

I'm experiencing discomfort or rubbing in specific areas.

Check your lacing technique to ensure it's not too tight or too loose. Experiment with different lacing patterns if you have specific pressure points. Also, ensure your running socks are seamless and fit well to prevent friction. If discomfort persists, consult a running specialist for a gait analysis.

The outsole seems to be wearing down quickly.

The `Continental™ rubber outsole` is designed for durability. However, wear patterns can indicate aspects of your running form. Ensure you are running on appropriate surfaces (roads, paved paths) as trail running or excessive gravel can accelerate wear. Regular rotation with other running shoes can also extend their lifespan.

Pros and Cons

Pros

  • Propulsive feel for efficient, faster training runs
  • Excellent balance of lightweight cushioning and durability
  • Targeted support and flexibility enhance comfort and stability
  • Breathable upper keeps feet cool over long distances
  • Reliable grip and long-lasting outsole performance
  • Made with a significant percentage of recycled materials

Cons

  • Specialized for mid- to long-distance, might be less versatile for other running types
  • 7 mm drop may not suit all runners' preferences or biomechanics
  • "Race-day feel" might be too aggressive for purely casual or recovery runs

Setup

Setting up your adidas Adizero Boston 12 shoes is straightforward:

  1. Lace Up: Utilize the standard lace closure system to secure the shoes to your feet. Ensure the laces are snug but not overly tight, allowing for proper blood circulation and comfort.
  2. Standard Fit: The shoes feature a standard fit. If you are unsure of your size, consult adidas' sizing guide. For UK 11 (29.5cm), ensure there is about a thumb's width space between your longest toe and the end of the shoe for optimal comfort during running.

Compatibility

These shoes are designed for adult male runners, specifically in the UK size 11 for this variant. They are optimized for mid- to long-distance running on roads and paved surfaces.

Care

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

  • Cleaning: To clean the lightweight mesh upper and `Continental™ rubber outsole`, gently wipe them with a damp cloth and mild soap. Avoid harsh chemicals or abrasive brushes that could damage the materials. Do not machine wash or tumble dry.
  • Drying: After cleaning or running in wet conditions, allow the shoes to air dry naturally at room temperature. Remove insoles to speed up drying and prevent odors. Avoid direct sunlight or artificial heat sources, as this can degrade materials.
  • Storage: Store your shoes in a cool, dry place away from direct sunlight when not in use. Avoid compressing them under heavy objects, which could alter their shape.
  • Insoles: Periodically remove and air out the insoles to maintain freshness. They can also be hand-washed if needed.
