How do I clean my Nike Alphafly 3 trainers?
Use a soft brush or damp cloth with mild detergent to clean off dirt, then air dry away from direct sunlight.

Troubleshooting
Foot feels constricted or tight
The Alphafly 3 runs small; if not already done, consider trading for a half-size larger pair.
Heel slippage while running
Adjust the slotted lacing system to ensure the midfoot is securely locked down, and ensure the tongue is centered properly.

Setup, Compatibility & Care
Before taking your first run, ensure you have correctly adjusted the slotted lacing system to suit your foot volume. Given that the shoes run small, confirm your fit by testing them with your preferred performance socks. To maintain the structural integrity of the ZoomX foam and the carbon-fiber plate, avoid machine washing or drying your trainers. Instead, clean the outsole and upper with a damp cloth and mild soap, then allow them to air dry away from direct heat sources. Store the shoes in a cool, dry environment to extend their lifespan.
