How long do frontside boots last?

With proper care, the shell of a frontside boot can last 150–200+ days of skiing. The liner typically needs replacement after 80–100 days as it packs out and loses its precise fit. Signs that your boots need replacement include visible shell cracking, significant liner pack-out that cannot be solved by buckling tighter, and flex that has softened noticeably from when the boots were new. The PU shell material used in most frontside boots is very durable and maintains its flex characteristics well over time.
