Refer to the PUMA sizing chart available on the product page or in stores. It's recommended to measure your foot length and compare it to the chart. For race shoes, a snug but not tight fit is often preferred.

The lifespan varies based on usage, terrain, and individual running style. For race-specific shoes like these, many runners use them primarily for races and key speed workouts to preserve their performance characteristics, typically lasting for 200-300 miles of race/speed work usage.

These are elite racing shoes, best suited for experienced runners or those specifically looking to improve their race times. Beginners might find more benefit from a more versatile or forgiving trainer for daily use.

Loosen the laces and re-tie them, ensuring even pressure distribution. If still uncomfortable, consider if this is the correct size or if the break-in period is needed for your foot shape.

These shoes are optimized for speed; consider if they are the right model for your intended distance. Ensure proper lacing technique and consider if a different shoe might be better suited for very long training runs.
