Seek out the serial number. On the inside lining of your fabulous shoe, you should spot an eight-digit serial number. The serial number is often found next to the shoe's size. If you do not detect a serial number in your supposed Gucci, kick those fake shoes to the curb.
Look inside the shoe for the Gucci name and country of origin. Authentic Gucci kicks will state "Gucci Made in Italy." If your shoes are lacking any or all parts of this important detail, or if yours differ in any way, you likely have a phony pair of kicks on your hands, or feet.
Scope out the soles. Gucci shoes are high-class honeys and are made of the finest materials. Even the soles, whose only purposes are to tread on the ground, are made out of high-quality leather. If the soles of your shoes feel like rubber or any material other than leather, they are likely fake and don't deserve to sit on your lovely piggies.
Inspect the dust bag in which your sassy shoes arrive. If your shoes are real, they will come in a dark brown bag that features the signature double "G" logo. If your bag comes in any other color or features a different design, your shoes are probably counterfeit, and if your shoes are missing the bag, you know they are phony.
Ask yourself if the cost makes sense. As of March 2011, most Gucci sneakers are in the five hundred dollar range, whereas heels and boots typically cost at least a thousand big ones, depending on their style. If you think you are about to make a killing on a pair of shoes by only paying 50 bucks, it is more likely that you are about to get ripped off.
Visit the Gucci website and study the shoes you desire. Print out a picture and take it with you when hitting the store. Doing so will make you more familiar with your shoe and better likely to spot a knock-off.
Purchase your shoes from the Gucci website to avoid being ripped off.
