A holistically improved shoe that incorporates beneficial aspects relating to a variety of interconnected elements, including comfort, sustainability, washability, ease of manufacturing, style, freedom and natural movement of the foot, as well as the sensory experience of a user. The shoe contains a removable insert that is configured to be removed and washed in between uses or as needed, such that a sock or other liner is unnecessary. The shoe further includes a footbed and an outsole that contain matching tread patterns. The matching tread patterns of the present technology allow the footbed and the outsole to move in concert by splaying during a stride in order to better absorb shock by mimicking the natural movements of the foot.
