If someone slips, for instance, the insole can detect that and alert a manager or supervisor. Of course, the whole system comes together in an app, where users can view detailed, real-time information and share it with other people. The same technology can be built into a shoe's midsole, according to Zhor Tech, but right now there are only plans to sell the insole to companies that make safety-conscious footwear. We're told it will ship in September for $149.
