Setup, Compatibility & Care
To ensure the longevity of your Nike Flex Trainers, proper maintenance is key. Since these feature a mesh upper, avoid heavy mud or extreme wet conditions. To clean, remove loose dirt with a soft-bristled brush, then wipe the surface with a damp cloth and mild soap. Avoid machine washing or using high-heat drying, as this can degrade the foam midsole. For the best fit, ensure you are wearing athletic socks that match the thickness you plan to use during training. The size 12 UK variant provides a standard performance fit consistent with other Nike athletic footwear.
