The Launchpad is a series that introduces Mashable readers to compelling startups. If you would like to have your startup considered for inclusion, please see the details here. While out and about, you notice a pair of shoes that you like. Maybe they're on a shelf in a store; maybe they're by your coworker's desk on the floor. You pull out your phone, take a picture, and an app helps you track down those shoes or another similar pair.
