Setup, Compatibility & Care
To ensure the longevity of your Nike Flex Train trainers, it is recommended to wear them primarily for indoor or flat-surface gym activities. When sizing, ensure a snug fit around the midfoot and heel, as the elastic band is intended to support the foot during side-to-side motions. For maintenance, keep the shoes clean by wiping the upper with a damp cloth and mild soap; avoid putting them in a washing machine, as the heat and agitation can degrade the adhesive and foam properties. Allow them to air dry naturally away from direct heat sources like radiators to preserve the materials.
