How to Clean ASICS GEL-Kayano Running Shoes

Step-by-step instructions

Step 1: Check the upper and damage first

Confirm that the pair has the usual mesh or knit upper rather than leather, suede, or a waterproof membrane. Inspect glued overlays, the heel counter, outsole edges, and exposed cushioning. If a bond is already separating, keep water away from it and consider repair or replacement; scrubbing and wetting can enlarge an existing failure.

Step 2: Remove laces and sockliners

Unlace fully and lift out removable sockliners so the upper, laces, and insoles can be cleaned independently. This reduces trapped detergent and lets each component dry. Do not force out an insole that is clearly bonded in place. Shake loose grit from inside before adding any water.

Step 3: Let mud dry and brush it away

If the outsole is muddy, allow the mud to become dry enough to crumble. Tap the shoes together gently and use a dry paper towel or brush to remove clinging soil. Pick small stones from the tread with a blunt tool. Removing grit dry keeps it from turning into slurry that works deeper into mesh.

Step 4: Mix a mild washing solution

ASICS recommends a bowl or bucket of warm water with roughly 15–30 ml of mild detergent. Use less solution for a small clean and avoid hot water, chlorine bleach, solvent stain removers, and fabric softener. Do not pour concentrated detergent directly onto the upper, where residue can stiffen fibers or leave a ring.

Step 5: Hand-clean the outsole

Dip a soft toothbrush in the solution and scrub the rubber tread, flex grooves, and sole edge. Keep the shoe above the bowl rather than submerged. Wipe away dirty foam with a wet sponge or towel. Do not aggressively scrub exposed foam or decorative GEL areas; clean them with a soft cloth and light pressure.

Step 6: Wash the mesh upper gently

Use a sponge or soft cloth moistened with solution to work across the mesh and overlays. Support the fabric from inside and use small passes instead of crushing the toe box. ASICS advises gentle scrubbing and says not to submerge the whole shoe. Treat the collar lightly so it does not become waterlogged.

Step 7: Clean laces and insoles separately

Massage laces in the mild solution, then rinse. For sockliners, use a soft brush with mild soap and water, rinse until suds are gone, and press them between towels without twisting. If an insole remains sour after cleaning and complete drying, replacement may be more effective than using strong disinfectant.

Step 8: Remove soap and air-dry

Wipe the upper repeatedly with a clean damp sponge until no foam remains. Stuff the shoes loosely with white paper towels or dry washcloths to hold shape and draw moisture, replacing them when saturated. Air-dry every component separately in shade. Never use a tumble dryer, heater, or strong sun; heat can distort foam and weaken adhesives.

Step 9: Reassemble and inspect

Wait until the sockliners, heel lining, and toe are completely dry before reinstalling anything. Brush dried residue away, check that the outsole and overlays remain secure, and lace without overstretching the eyelets. Future maintenance is easier if mud is brushed off after runs and shoes are allowed to ventilate between wears.
