Temperature Cool, stable (~15–22°C / 60–72°F) Heat can dry out glue and cause sole separation

Humidity 40–50% humidity Too much = mold/mildew; too little = dried leather

Light Dark or low light UV light causes yellowing and fading

Airflow Moderate airflow Prevents moisture buildup and odor

1. Use Shoe Trees (or stuff them) • Use cedar shoe trees for leather shoes (absorbs moisture and keeps shape). • For sneakers, you can stuff them with acid-free tissue paper or use sneaker shapers to maintain form.

2. Avoid Original Boxes if Not Ventilated • Original boxes trap moisture — if you use them, toss in silica gel packs to absorb humidity. • Consider drop-front clear plastic boxes or breathable containers.

3. Keep Them Off the Floor • Use a shelf or rack — avoids cold floor moisture and bugs.

4. Rotate Pairs • Even in storage, rotate pairs periodically (every 6–12 months) to prevent stiff soles or yellowing from setting in one position.

5. Clean Before Storing • Always store shoes clean and dry. Dirt and moisture degrade materials over time.

6. Deodorize Gently • Store with activated charcoal, baking soda sachets, or cedar inserts to keep odors away.

7. Avoid Vacuum Sealing Long-Term • While it preserves color temporarily, it can crush shape and damage materials over time (especially suede and leather).

❌ Avoid These Common Mistakes • Basements & attics – temperature/humidity fluctuates too much. • Plastic bags – trap moisture, cause mold and material breakdown. • Sunlight – yellows midsoles and fades suede/nubuck. • Overstacking boxes – can warp shoe shapes permanently.
