Last month I walked into a Goodwill, spent $12 on a pair of beat-up 2003 Nike Dunk Lows, cleaned them up, and sold them for $415 on eBay.

Most people walk right past these shoes. They don't know what they're looking at. That's the edge.

Here's the quick breakdown of how vintage sneaker flipping works:

1. Know what to look for. Not every old shoe is worth money. You need to recognize silhouettes, colorways, and era-specific details. A 2004 Air Force 1 in a rare colorway? That's money. A 2019 Roshe? Skip it.

2. Source cheap. Thrift stores, garage sales, estate sales, Facebook Marketplace. The best deals are where sellers don't know what they have. I've found $300+ pairs at Goodwill for under $15.

3. Authenticate and condition. Buyers pay premium for verified authentic pairs. Learn the stitching patterns, box labels, and material tells. Clean them properly — a $5 cleaning kit can add $100 to your sale price.

4. Price and list smart. Check sold comps on eBay and StockX. Price 10-15% below the last sale for a quick flip, or hold for the right buyer if it's a rare pair.

The vintage sneaker market is booming because supply is drying up — these shoes aren't being made anymore. Every month there are fewer pairs in good condition.
