Cleaning Foamposites
The Foamposite upper is a one-piece molded polyurethane shell — completely sealed and surprisingly easy to clean. A damp microfiber wipes off most marks. The risk areas are deep scuffs (almost impossible to repair) and the inner foam degrading over years of storage.
Overview
How often
Wipe with a damp cloth roughly every 30 wears, or whenever it's marked. No conditioner or protector.

Step by step
Step 1: Wipe with damp microfiber. Plain water only
No cleaners, no conditioners, no protectants of any kind.
Step 2: Never brush
Brushes scratch the PU finish. The signature high-gloss look of a fresh Foamposite is the finish — abrade it and the shoe looks dull permanently.
Step 3: Never apply heat
No hair dryers, no direct sunlight drying, no garage storage in summer. PU is heat-sensitive.
Step 4: No conditioner
Foamposite isn't leather. Leather conditioners can leave permanent oily marks on PU shells.
Step 5: Severe finish dulling
Accept some dulling. A dry, clean microfiber buff is the most you should do. Polishes and compounds, headlight polish included, are abrasive and strip the gloss for good.
What to avoid
- Any brush — it dulls the finish permanently
- Cleaners, conditioners or protector sprays — plain water only
- Heat, hot cars or summer garage storage
- Storing it creased or flexed
Watch for
- Foamposite year 5 10. Wear it less and keep storage cool and dry.
- Foamposite year 10 15. Wear it sparingly; the shell is near the end of its life.
- Foamposite year 15 plus. The pair is at the end of its life.
By material
The routine above, adjusted for each material it covers.
Foamposite
Aging varies by color: black and Pure Platinum show dulling less than colored or metallic finishes. Galaxy, Eggplant and Royal pairs with painted graphics can flake paint separately from the shell. Eggshell and cream finishes yellow under UV — keep them in the dark.
Between wears
- Climate critical. Climate control matters. A Foamposite in a humid garage in Houston ages fast; the same pair in a climate-controlled closet lasts much longer.
- Environment. Cool, dry, dark. All three matter.
- Humidity. Silica gel packets inside the box for any climate above 50% humidity. Replace every 6-12 months.
- Original box. The original box works well for storage. Keep it intact.
- Flex position. Don't store in flex position. Stuff with paper to maintain the shell's natural shape. Prolonged flex at one point creates a stress concentration that becomes the first crack site.
- Rotation. Take stored pairs out every 6-12 months — even boxed pairs benefit from some air.

Cleaning Plastic Cages & Overlays
Clear plastic cages on Air Max 95s and 97s, hardware overlays on Jordans — these don't get dirty so much as damaged or yellowed by UV. Care is mostly prevention: store them away from direct sun, clean gently, and accept that some yellowing is part of the journey.
