System and methods for lasting an upper to a 3D printed platform

A shoe comprising:

• a fastener;
• an upper comprising a first upper side, a second upper side opposite the first upper side, and a plurality of fastener channels configured to receive the fastener;
• and
• a platform comprising:
• a first surface configured to support a user foot,
• a second surface opposite of the first surface,
• a first side portion extending between the first surface and the second surface,
• a second side portion extending between the first surface and the second surface, the second side portion opposite the first side portion,
• a first bevel defined in the first side portion and configured to receive a portion of the first upper side of the upper,
• a second bevel defined in the second side portion and configured to receive a portion of the second upper side of the upper,
• an internal channel positioned between and internal of the first surface and the second surface and between the first and second side portions, wherein the internal channel forms a loop-shaped path that extends between the first bevel and the second bevel and between the first and second side portions, wherein at least a portion of each of the first bevel and the second bevel provides access openings to the loop-shaped path of the internal channel, the internal channel is configured to receive the fastener to assemble the upper with the platform with the portion of the first upper side fastened in the first bevel and the portion of the second upper side fastened in the second bevel;
• and
• a sock liner;
• wherein the platform comprises a slot extending around the platform at an outer perimeter of the platform, wherein an edge portion of the sock liner is retained within a slot of the platform.
