Phillip:
When you refer to the ILA is this the medial longitudinal arch?
In my inquiry I was refering to forefoot extrinsic posts (tip or corner) that are fastened to the distal end of the shell. My interest, similar to yours, is how does the addition of extrinsic posts affect the rigidity of the shell. We believe that the addition of an extrinsic forefoot or rearfoot post, or both, increases the overall rigidity of the device when compared to a stand alone shell with only intrinsic posting.
Thanks, Mac
