The XT-900 rubber is known for its durability and traction, offering good wear resistance for a performance-oriented shoe used on various road surfaces.

The lifespan of cushioning varies based on mileage, weight, and running surface, but typically performance foam like PWRRUN PB is expected to perform well for 300-500 miles. Regular inspection for wear and tear is advised.

Ensure the laces are loosened before putting them on. Adjust the lacing pattern to provide more volume or alleviate pressure points. FORMFIT technology will adapt over time, but initial tightness can sometimes be managed with lacing techniques.

Try a runner's knot (a specific lacing technique) to secure the heel. Ensure the lacing goes through the additional eyelet at the top of the shoe for a more locked-down fit.

Check for any debris or wear on the outsole that might affect traction. Ensure the shoe has not been exposed to extreme temperatures, which can affect foam performance. Regular cleaning can also help maintain optimal performance.

This can sometimes occur with new shoes. Wear them for shorter durations initially to allow the upper to soften and adapt to your foot's shape. Ensure socks are worn to prevent chafing.
