As mentioned in the "About Us" section, Jezign has 2 patents for our manual on/off switch on illuminated footwear soles. Unfortunately, foreign manufacturers have developed an inferior and illegal imitation to Jezign's patented technology. Below is an example of what some of these imitations look like. As you can see, these knockoffs are cheap and have a do it yourself look. The lights are glued all the way around the shoe as opposed to building the shoe around the illumination system in the way that Jezign does. As you will also notice, they are not performance shoes. Don't support these knockoffs. Lightning Footwear, TGB and Zigi are the only official licensees of the Jezign technology. Jezign is currently taking steps to enforce our intellectual property rights.
