Buying & Selling Secondhand Sneakers: 7 Things to Know Before You Lose Money

The secondhand sneaker market in Vietnam is growing fast. From Facebook groups to Carousell, from sneaker cafés to professional consignment stores — used shoes are now a real market with its own rules.

But in this market, plenty of buyers overpay, and plenty of sellers undersell simply because they don't know how to prep a pair before listing it.

For Buyers: 4 Things to Check

1. Inspect the Sole Glue Lines

This is the most important area most people skip. Press gently along the edge of the sole — if you see gaps or lifting glue anywhere, the shoe could open up within weeks.

Repair cost: Professional re-gluing at EXTRIM starts at 80,000–200,000 VND — but if you didn't spot it beforehand and negotiate the price down, that's money out of your pocket.

2. Smell the Inside

A damp, musty odor inside a shoe isn't just a hygiene issue — it can signal that mold has already penetrated the foam footbed, which requires costly deep treatment.

3. Check Sole Wear

Flip the shoes over and look at the outsole:

• Even wear on both sides: normal, the pair is simply aging
• Uneven wear on one side: the previous owner may have a gait issue (pronation/supination), and the structure has been affected

4. Match Tags to the Version

For Nike, Adidas, and New Balance: the SKU on the tongue tag must match the box label. No box? Verify the SKU with an app like CheckCheck or a Google search to confirm the model and production year.

5. Clean Before You Sell — Small Investment, Big Return

A clean, fresh-smelling pair can sell for 20–30% more than the same pair in dirty condition.

Before cleaning	After cleaning
Dirty Jordan 1	Actual condition must be assessed before pricing
Stained New Balance 990	Actual condition must be assessed before pricing

Cleaning costs just 120,000–200,000 VND, but can add 300,000–500,000 VND to the sale price. An investment that pays for itself instantly.

6. Good Photos = Faster Sale

• Shoot on a white or light wood background
• Capture all 6 angles: front, back, both sides, sole, interior
• Take close-ups of any stains or damage (if present) — transparency builds trust

7. Keep All the Accessories

Original box, dustbag, tags, extra laces, receipt... each one adds resale value. Especially for branded shoes:

• Box + tags: +15–20% value
• Authentic receipt: +10% value
• Full accessory set: up to 25–30% total

EXTRIM — Partner to the Secondhand Sneaker Community

Many professional secondhand sellers work with EXTRIM to prep inventory before listing:

• Deep cleaning — shoes look sharper and more presentable
• Sole de-yellowing — white soles restored, boosting visual appeal
• Color restoration — covers minor scratches
• Deodorizing — completely removes the previous owner's foot odor

Cleaning services from 120,000 VND. Small investment, potentially hundreds of thousands of VND more on the sale.
