There are several ways to check if sneakers are fake. You should always closely examine the packaging, box tag, and tags inside the shoes to verify they are legit. There’s also often a verification process when you buy or sell sneakers through a secondary sneaker resale website. The process typically involves the seller shipping the shoes to the resale marketplace for a physical inspection. This can add several days to the shipping process, but it also ensures you aren’t buying fake sneakers.
