adidas UltraBoost 22 - Cloud White - UK 4

The Primeknit upper offers a degree of adaptive stretch, which can accommodate some wider feet. However, if you have significantly wide feet, it's advisable to try them on first or consider shoes specifically designed for wider fits.

The UltraBoost 22 features an updated last for an improved fit, particularly for women, and incorporates more recycled materials in its construction. The core Boost technology and overall performance remain highly regarded.

Use a soft brush or damp cloth with a small amount of mild soap and cool water. Gently scrub the affected areas and wipe clean with a separate damp cloth. Avoid abrasive cleaners or excessive water saturation.

While the cushioning is excellent for running, the UltraBoost 22 is primarily designed for running. For cross-training activities that involve lateral movements, a shoe with more lateral stability might be more appropriate.

Using recycled materials helps reduce waste and the environmental impact of production. The Primeknit upper in the UltraBoost 22 contains at least 50% recycled polyester and 50% recycled cotton.

The Boost midsole is known for its durability and resistance to temperature changes. While it offers excellent performance for many miles, most runners find its optimal responsiveness lasts between 300-500 miles before gradual decline.

This can sometimes occur due to moisture between the sole components or the insole. Try removing the insole and ensuring both it and the inside of the shoe are completely dry. A light dusting of talcum powder under the insole may help.

Adjust lacing for a more personalized fit. Ensure you have selected the correct size; refer to sizing charts if unsure. The Primeknit upper will offer some stretch, but a fundamentally incorrect size cannot be compensated for by lacing.

While Boost technology is durable, performance can slightly diminish after extensive mileage (typically 300-500 miles). Consider replacing the shoes if performance significantly degrades.
