Setup, Compatibility & Care
To ensure the longest lifespan for your Challenger 8 trainers, follow these maintenance tips. Always remove excess mud or debris after a trail run using a soft-bristled brush, as drying mud can degrade the mesh fibers over time. If the shoes become very wet, remove the insoles and stuff the interior with paper towels to draw out moisture in a well-ventilated area—avoid placing them directly on heaters or in direct sunlight, which can cause the foam midsole to warp or harden. If you use custom orthotics, the factory insole is removable to ensure a proper fit for your medical inserts.
