Real Adidas items are uniformly and neatly stitched. Fake ones will have shoddy and loose stitch work. Uneven stitching often makes it easy to spot a fake Adidas product.

Look for the tag on the product which will have the size and other product information mainly inside the shoe that is behind the tongue of the shoe. Real Adidas shoes have tags with serial numbers for the left and right shoe. However, a fake product will have the same serial number on both shoes.

But it's Adidas' headquarters in Herzogenaurach, Germany where the brain child of development resides. Here new materials and designs are created and tested by a team of shoemakers, robots and athletes to get the shoe right before the design is ready to be sent through to the manufacturing process.
