For the PRIMEKNIT upper, gently brush off loose dirt. Then, use a mild soap solution with lukewarm water and a soft cloth or sponge to gently scrub the material. Wipe off soap residue with a clean, damp cloth and air dry completely away from direct heat.

BOOST technology is adidas's innovative midsole cushioning system made of thermoplastic polyurethane (TPU) pellets. It provides exceptional energy return, responsive cushioning, and durability, offering a 'springy' feel that helps reduce fatigue and enhances comfort with every step.

Yes, the adidas Ultraboost 1.0 demonstrates a commitment to sustainability. The yarn in the upper contains at least 50% Parley Ocean Plastic and 50% recycled polyester, contributing to efforts to reduce plastic waste.

The Continental Rubber outsole, combined with the Stretchweb design, provides superior grip and traction on a variety of surfaces, including wet and dry conditions. This enhances safety and confidence during movement, making the shoes more dependable.

The Ultraboost 1.0 generally fits true to size. However, given the adaptive nature of the PRIMEKNIT upper, some prefer a snug fit. It's always recommended to try on shoes if possible to ensure the best comfort, especially considering your typical sock thickness.

No, machine washing is not recommended as it can damage the materials, adhesives, and overall structure of the shoes. Always clean them by hand using the gentle methods described in the 'Care' section.

Ensure the laces are not tied too tightly. The PRIMEKNIT upper is designed to be adaptive, but over-tightening can cause discomfort. Try adjusting the lacing pattern or loosening them slightly. Verify you have the correct size; shoe sizes can vary between brands.

Check the Continental Rubber outsole for accumulated dirt, mud, or small stones lodged in the Stretchweb pattern. Clean the outsole thoroughly with a brush and water to restore optimal traction. If wear is significant, the outsole might be nearing the end of its life.

A common cause is moisture trapped between the insole and the shoe's footbed. Remove the insoles and clean both the insoles and the inside of the shoe. Ensure they are completely dry before reinserting. Alternatively, a loose component inside the shoe or a faulty bond can cause squeaking; if persistent, contact customer support.

The BOOST material can attract dirt. Use a mild soap solution and a soft brush or cloth to gently scrub the affected areas. White shoe cleaner or a magic eraser can also be effective for tougher marks on the foam, but test on an inconspicuous area first.

Ensure the Fitcounter moulded heel counter is properly engaging your heel. Re-tie your laces, paying attention to a secure knot. You might also try a 'runner's knot' lacing technique to better lock your heel in place. Check your sock thickness, as thinner socks can sometimes contribute to slippage.
