If the set GPS route requires the user to turn left, the left Lechal insole with vibrate which informs the user they should take left. The company originally developed the device to be used by visually impaired persons, but later expanded to regular users.

The insoles utilize small wireless, baterry-powered devices called "Pods". These are steel encased vibration motors and inertial sensors that are attached to Lechal shoes or inserted into insoles.
