Setup, Compatibility & Care
To ensure your trainers last, proper maintenance is essential.
- Initial Setup: Ensure you choose the correct size based on your standard UK measurement for the most secure fit.
- Cleaning: Use a soft-bristled brush and mild soapy water to remove surface dirt. Avoid machine washing or using harsh chemical cleaners that may damage the midsole foam.
- Storage: Keep the shoes in a cool, dry area away from direct sunlight when not in use to prevent material degradation.
- Drying: Air dry the shoes naturally; never place them on a heater or near an intense heat source, as this can warp the foam.
