Daily after wear: Tap the soles together 3-4 times to shake off grit; immediately wipe the knit along its grain with a dry microfiber cloth to stop dust from embedding. Deep clean: Remove laces, dip a soft toothbrush in a mix of 1 L cold water + 3 drops neutral detergent, and gently scrub the upper and tongue in circles; wipe away suds with a barely damp cloth—never soak. Midsole care: Use a gum eraser or foam cleaner on rubber edges and groove crevices to remove oxidation; for stubborn black marks, lightly brush with a baking-soda paste, then wipe clean. Drying shaping: Stuff the shoes with ink-free white paper or a clean towel to hold form and absorb moisture; air-dry in a ventilated shaded spot—no direct sun or hair-dryer heat to prevent knit shrinkage or sole separation. Deodorize: Once fully dry, spritz a shoe-specific deodorizer inside or leave an activated-charcoal pouch overnight; replace the pouch every two weeks to keep interiors . Protection boost: With the upper completely dry, spray a thin, even coat of fabric protector for synthetics from 20 cm away; apply two light layers 30 min apart to repel rain and oil stains. Storage rotation: When not in use, place the shoes in their original non-woven bag inside a dry cabinet; avoid stacking heavy items on top to keep the thick sole from deforming. For long-term storage, air them out and re-spray protector every two months.
