Abstract: A door system having a door shoe including a first shoe member and a second shoe member that provide a thermal break between the members, which reduces heat transfer between the members. One or more gaskets may be operatively coupled to the first shoe member or the second shoe member. The first shoe member and the second shoe member can be operatively coupled to the door to cover different sized gaps located between the bottom edge of the door and a floor. As such, the door shoe disclosed herein may be used to cover different size gaps, provide a thermal break between the members to aid in fire resistance, and be easily installed on doors without having to remove the door from the frame.
