What is the maximum degree for a rear foot varus post?

The maximum degree for a rear foot varus post is 4 degrees. This amount is considered sufficient to correct for rear foot varus, which is a condition where the heel tilts inward while the forefoot remains in a neutral position. Typically, a rear foot varus post helps to realign the foot during the stance phase of walking or running, providing support and stability.

Using a post greater than 4 degrees can lead to excessive compensation in the subtalar joint, which may create discomfort or lead to other foot problems. Post adjustments must be carefully considered because the subtalar joint's motion and stability are directly affected by the degree of rear foot posting. Hence, in practice, it is important to adhere to this maximum to ensure optimal foot function and patient comfort.
