Tip 3: All genuine Adidas products have serial numbers on the tags affixed to them. The tags have the size and product information on the inside of the shoe (behind the tongue).

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.

This ridiculously lightweight running shoe is 33% lighter than Nike's Vaporfly. At 138 grams, it weighs as much as a single D battery, but we also loved its bouncier foam underfoot, which provides great energy return while running long distances.

The serial number on the underside of the tab must match the serial number on the box. The brand uses its cloverleaf logo in a print on the tongue and not a sticker like the counterfeits. The finishing of the sneakers adidas Originals is of high quality. Most models have simple holes instead of eyelets.
