FAQ

Do you sell sneakers or take a cut of my sales?

No. SizeRun is software. You sell on your own marketplace accounts and receive payouts directly from them. We only charge a flat subscription fee.

How does oversell protection work?

Each pair has one quantity shared by all your listings. When an order comes in, SizeRun records it once and then lowers or removes your other listings for that item. If a marketplace call fails, it retries and shows the issue in your dashboard.

Is my marketplace account safe?

We connect through each marketplace's official authorization where available, store credentials encrypted, and you can disconnect at any time.

Can I cancel anytime?

Yes. Cancel from the billing page and you keep access until the end of the period you've paid for.

Who is behind SizeRun?

SizeRun is built and operated by Yuemas Technology LLC, a software company with years of experience building sneaker warehouse and marketplace systems.
