SKU stands for 'Stock Keeping Unit' - It's used by stores to keep track of inventory. Cyber uses the SKU to find/checkout items on the following stores:
All Mesh Stores (JD Sports, Size?, Footpatrol, Hip Store)
All Footsites (Footlocker UK/CA/US, Eastbay, Champs, Footaction)
You can find the mesh SKUs in the appropriate 'scraper' channel inside out Discord.
And you can locate footsite SKUs directly from the websites themselves in the product URL, for example:
The SKU would be '314107829104' for the above product.
We always provide the SKUs in our release guides regardless, so you don't have to worry about finding them yourselves!
