After assessing the amount of posting
required, the Medafeet MOSI rearfoot
post can be ground to supply this
quickly and easily.

Simply use the layered rearfoot post as
a guide. Grind off one, two or three
layers to reduce the post to the optimal
level for your patient with a medically
deviated Subtalar Joint axis.

One post reduction, a Moderate MOSI post

No post reduction, a large MOSI post

Two post reduction, a small MOSI post.

Three post reduction, a flat MOSI post.
