Wallapop to StockX: Where Your Unworn Sneakers Can Go Next
Which Wallapop stock StockX will take, what its fees come to on a €150 pair, and what to do on each side after a sale.
Most Wallapop stock has no place on StockX. The exception is a pair of sneakers still in the box, or a sealed collectable, that a buyer outside Spain, Italy and Portugal would pay more for. FLUF Connect places a StockX ask from your Wallapop inventory and ends it if the item sells on Wallapop first.
In short
- StockX’s Verified Marketplace takes new, unworn items, and checks each one before it reaches the buyer.
- Wallapop charges sellers no commission. A new StockX seller pays 9% plus 3%, or €18 on a €150 pair, with a €5 minimum in the EU.
- A Wallapop sale ends the StockX ask.
- FLUF does not see a StockX sale. Mark it sold in FLUF, then delete the Wallapop listing yourself.
What fits and what does not
| Send to StockX | Keep on Wallapop |
|---|---|
| Unworn sneakers in the original box | Worn sneakers and used clothing |
| Sealed collectables with a StockX product page | Furniture, bikes and anything collected in person |
| New streetwear with tags | One-offs with no StockX product page |
StockX’s verification guide explains how it checks each item. A pair that fails because it is worn or lacks its box does not sell, so be strict about what you send.
What a €150 pair earns
Wallapop’s seller FAQ says it takes no commission for posting an item or completing a sale. On a shipped sale, the buyer pays handling, protection and postage. StockX’s seller fees page sets a 3% processing fee plus a transaction fee that falls from 9% at Level 1 to 7% at Level 5.
| €150 pair | On Wallapop | On StockX, Level 1 |
|---|---|---|
| Seller fee | €0 | €18.00 |
| You keep, before any postage | €150.00 | €132.00 |
| Likely price | What a local buyer will agree to in chat | Your ask against the lowest ask on the page |
At the same price, Wallapop always wins. StockX pays off only when the market price is at least €18 above what you can get locally, and a rare size or a release that did not reach Spain is the usual reason. Check the lowest ask and recent sales on the product page first. Wallapop’s terms limit it to Spain, Italy and Portugal, which is where StockX’s wider audience comes in.
How to send Wallapop items to StockX
- Connect Wallapop in FLUF Connect. You sign in once, in the FLUF browser extension or the FLUF mobile app, and your listings appear in your FLUF inventory.
- Connect StockX from the Channels screen.
- Filter the inventory to Wallapop, select the new and boxed items, and choose StockX as the destination.
- FLUF looks for each item in the StockX catalogue. If there is no match, or several close ones, choose the exact product and size yourself.
- Set your ask and publish.

Your Wallapop photos and description do not travel. A StockX ask sits on StockX’s own product page, with its photos and details, so the product and size are what matter. Wallapop listings often use EU sizes, and a pair listed under the wrong size will fail verification, so check the size scale on the product page.
After a sale
| What happens | Result |
|---|---|
| It sells on Wallapop | FLUF picks up the sale and ends the StockX ask |
| It sells on StockX | FLUF does not see it. Mark it sold in FLUF and delete the Wallapop listing yourself |
| You change the ask in FLUF | The StockX ask is updated |
| You want to relist on Wallapop | Available through FLUF on Pro and above |
Watch StockX most closely. Nothing stops a Wallapop buyer messaging you about a pair that sold there an hour ago, so check for StockX sales before you agree a meeting. Offer management is not available through FLUF on either channel.
What FLUF costs
Crosslisting, inventory sync and order sync are on every FLUF plan, from £9 a month for Starter. Relisting, offer management and smart pricing come with Pro and above. You can start with 7 days for £1, then from £9/month.
