## Description

These Boot-Wheels are constructed of high-grip silicone rubber that offers excellent grip against a multitude of surfaces. The plastic center core gives this wheel great positive drive when installed on an 8mm REX™ shaft, leaving only the axial constraint up to you.

With The “toe” of your Boot-Wheels spinning towards your robot, they’ll give your items a little kick up. With the “heel” of the boot spinning towards your bot, they’ll give you a more horizontal trajectory. A combination of orientations can lead to some very interesting intake geometry.
