My published theory from 15 years ago, the Subtalar Joint Axis Location and Rotational Equilibrium (SALRE) theory of foot function (Kirby KA: Subtalar joint axis location and rotational equilibrium theory of foot function. JAPMA, 91:465-488, 2001), has recently been supported in newly published research using valgus-wedged orthoses on subjects that had the electromyographic (EMG) activity of their lower leg muscles recorded. The authors found that peroneus longus EMG activity was reduced with foot orthoses that had valgus wedges added to the orthoses (Moisan G, Cantin V: Effects of two types of foot orthoses on lower limb muscle activity before and after a one-month period of wear.
