In this “Foot of the Week” episode, we talk about the evolution of the medial malleolar window in our custom brace design for post tib or posterior tibial tendonitis (PTTD or PTD). The Blaze MI brace includes a relief for the medial malleolus called a window, and since its origination, the shapes have changed. Now the brace even includes a relief or window for the navicular or any other prominent bone of the foot. This provides the required support while also providing the needed space and “give” when pressures and pain are high.
