Besides being smaller and lighter than the 2015-era Kat Walk, the new ‘mini’ design replaces the older wireless foot sensors with a laser sensor array set into the baseplate of the device, which is said to feature lower latency and provide more responsive input. Kat Walk Mini also features a redesigned guide bar system that pivots in place as you turn your body to face the desired direction. A “high strain shock-absorbing material” is used in the treadmill’s base, although we’re not sure how it differs from the original unit’s surface, or if that will require the user to user to don special low-friction shoes.
