Yes, they can be used for marathons, especially by runners who prefer a more responsive and less plush feel, and are accustomed to faster paces. They offer sufficient cushioning for the distance but prioritize speed.

Clean them with a damp cloth and mild soap after removing loose dirt with a brush. Avoid machine washing and ensure they air dry naturally away from heat.

The shoes utilize advanced midsole foam technologies designed to absorb impact and then return energy with each stride, contributing to a propulsive feel.

While comfortable, their design is optimized for athletic performance. For everyday casual wear, you might find other shoes offer more general comfort, but they are certainly wearable for light activity.

'Adizero' is Adidas's line of products focused on lightweight performance, aiming to help athletes achieve their best times by reducing weight and enhancing speed.

It's a traditional lacing system that allows for manual adjustment. You thread the laces through the eyelets and tie them to secure the shoe to your foot, enabling a customized fit.

Adjust the lacing system. Experiment with different lacing techniques or eyelet usage to find your optimal fit. Ensure the knot is secure but not overly tight.

Ensure the shoes are clean, especially the outsole, for optimal traction. Check for any signs of excessive wear on the midsole cushioning, which may indicate the shoe's lifespan is nearing its end.

Verify the lacing is not too tight in the midfoot, which can sometimes cause pressure on the toes. If the issue persists, the shoe's shape might not be compatible with your foot anatomy.
