When you see this, you should be thinking one of 3 possible etiologies...
/Cardinal sign of either a forefoot supinatus/forefoot varus or collapsing midfoot
I was hiking behind this young chap over the weekend along with my son and friends. Note the amount of calcaneal eversion present on the right side that is not present on the left. Also note the increased progression angle of the right foot and subtle circumduction of the extremity.
In my experience, you would generally see this much calcaneal diversion and one of three scenarios:
1. Moderate leg length discrepancy with the increased calcaneovalgus occurring on the longer leg side. This would support the amount of circumduction were seeing on the right side.
2. When there is a forefoot supinatus present and and inadequate range of motion available in the midfoot and/or forefoot. This is most likely the case here.
3. In moderate To severe midfoot collapse. This is clearly not the case as the medial aspect of the shoe is usually “blown out”.
Next time you see an everting rearfoot, think about these three possible etiologies.
