Additionally, in some embodiments, projections 1 10 may require an additional force to extend fully into alignment holes 1 102.
  • a vertical force 1300 may be exerted on fixture 100. Force 1300 may assist in pressing projections 1 10 into alignment holes 1 102 of sole 1 100.

Due to the geometry of the contact surfaces of members 108, a portion of the magnitude of the vertical force exerted on midfoot member 104 may be translated to a longitudinal force that extends along heel member 102 and forefoot member 106. A component of force 1300 that is exerted on midfoot member 104 may transfer to heel member 102 in a longitudinal direction represented by force 1302. Additionally, another component of force 1300 may extend through forefoot member 106 represented by force 1304.
