These boots were made for tracking
DARPA, everyone’s favorite organization that sounds suspiciously like Dharma, is working on tracking sensors that can be embedded into the sole of a shoe. Micro Inertial Navigation Technology, or MINT for short, is being jointly developed by Case Western University and Intersense (of the Massachusetts Intersenses). These sensors are designed to provide location information in places that satellite-based navigation services fail. Think inside caves in Afghanistan.
Intersense currently makes NavShoe
