What is the weight of these shoes?
The adidas Adizero Prime X2 Strung weighs 315g (for a UK 4.5, weight may vary slightly with size).
What is the stack height and offset?
The shoe features a substantial stack height of 50-43.5mm and an offset (heel-to-toe drop) of 6.5mm.
What does 'STRUNG upper' mean?
The STRUNG upper is an advanced textile construction where threads are precisely placed layer by layer to provide targeted support and expansion zones, creating a custom, locked-in fit around your foot.
How do I clean my Adizero Prime X2 Strung shoes?
Clean them by hand using a soft brush, mild soap, and cold water. Avoid machine washing or drying, and let them air dry naturally away from direct heat.
Are these shoes suitable for everyday training?
Yes, while engineered for performance, their exceptional cushioning and comfort make them highly suitable for everyday training, especially for long runs and recovery efforts where impact protection is beneficial.
What is Lightstrike Pro foam?
Lightstrike Pro is adidas's advanced cushioning foam, known for being lightweight, highly responsive, and providing significant energy return, making it ideal for high-performance running.
Troubleshooting
Shoe feels too high or unstable.
The high stack height takes some getting used to. Ensure your lacing is secure, focusing on the midfoot. Allow a few runs to adapt your gait. If issues persist, it may not be the ideal shoe for your stability needs.
Lacing feels uncomfortable or creates pressure points.
Experiment with different lacing techniques. Try skip-lacing (skipping one eyelet) over areas of high pressure, or use a runner's knot for a more secure ankle fit while loosening the forefoot.
Traction feels less effective on certain surfaces.
The Continental rubber outsole offers excellent grip, but no shoe is infallible. Ensure the outsole is clean from debris. For extremely wet or icy conditions, adjust your running style or consider shoes specifically designed for those extremes.
Foot discomfort or hot spots during long runs.
Check your sock choice; moisture-wicking running socks can make a big difference. Ensure the shoe size is correct – a common mistake is shoes being too small. Re-evaluate lacing. Allow proper break-in time for the shoe to mold to your foot.
Overall performance feels diminished over time.
Running shoe midsoles, especially high-cushion ones, have a lifespan. While durable, the foam will eventually compress. Consider the mileage you've put on the shoes. Regular cleaning and proper drying can help maintain material integrity.

Cons

Setup, Compatibility & Care
Initial Setup
- Lacing: The shoe features a standard lace closure. Experiment with different lacing patterns to find the most comfortable and secure fit for your foot. A snug midfoot with a little wiggle room for your toes is generally ideal.
- Break-In: While modern running shoes often require minimal break-in, it's always advisable to wear them for shorter runs before committing to a long distance. This allows the cushioning to adapt to your stride and ensures optimal comfort.
Compatibility
- Runner Profile: Designed for performance-focused runners, particularly those who benefit from significant cushioning and energy return. While listed as a 'Male' shoe, its performance-driven design makes it suitable for any runner seeking these specific benefits. (Note: Size UK 4.5).
- Terrain: Best suited for road and light, well-maintained trail surfaces due to the outsole's design and the shoe's high stack.
Product Care
To ensure the longevity and performance of your Adizero Prime X2 Strung shoes:
- Cleaning: Gently brush off loose dirt with a soft brush (like an old toothbrush). For tougher stains, use a mild soap and cold water solution with a cloth. Avoid machine washing or drying, as this can damage materials and adhesives.
- Drying: Allow shoes to air dry naturally at room temperature. Remove insoles to help them dry thoroughly. Do not expose them to direct heat sources like radiators or direct sunlight, as this can degrade materials.
- Storage: Store your shoes in a cool, dry place away from direct sunlight. Avoid compressing them for extended periods, as this can affect the midsole's integrity.
- Rotation: If you run frequently, consider rotating your Adizero Prime X2 Strung with other running shoes. This allows the foam to decompress and recover, extending the lifespan of the cushioning.
