Fresh Foam is a lightweight cushioning foam developed by New Balance, known for its high resistance to deformation, providing a soft feel and protecting joints during long runs.

With proper care and regular use on suitable surfaces, the outsole's durability is good. However, for optimal performance and cushioning, it's generally recommended to replace running shoes every 300-500 miles.

Ensure the lacing is adjusted correctly for a secure but not overly tight fit. Verify you have the correct size and that the shoe is suitable for your foot type (neutral/supinated).

While Fresh Foam is durable, cushioning can naturally degrade with extensive use. Consider replacing the shoes after approximately 300-500 miles of running, or when you notice a significant decrease in comfort and support.

The breathable mesh is designed to adapt. Ensure you are not over-tightening the laces. Allow the shoes to break in gradually if they feel stiff initially.
