Shoes are a fantastic idea, and highly overlooked. The biggest hurdle to wearable technology is the friction required to convince a consumer to wear it. We all wear shoes. We don't all wear glasses or watches. Some of us even wear contacts to avoid wearing glasses. The Smartshoe doesn't seem as competitive to Google Glass as it is complimentary. Glasses have a better appeal for visual media capture because you can see what you're capturing in real time and from a better angle. The Smartshoe could have a better appeal for fitness and GPS use cases. Emphasizing 'smartsole' would probably be a better sell than 'smartshoe' though. Letting consumers stick with their personal fashion choices, i.e. Nike, Vans, is a powerful selling point.
