The Base Model was designed to increase proprioception (perception or awareness of the position and movement of the body). Removing the outsole is a critical component of this shoe's design to achieve this goal.

Thus, we recommend using this shoe in your rotation every second day to prolong the lifespan while resetting your stride.
