I was in a discussion yesterday on my boot set up. I have limited dorsiflexion. Not horrible but enough for the fitter to note it. When the same fitter did my daughters boots, he stated she needed a stiffer boot because she has hyper-dorsiflexion. In my simple head - if hyper dorsiflexion needs stiff then limited dorsiflexion needs soft.
If all things are equal with two people except one has hyper and one has limited dorsiflexion, what would you expect them to get with regards to flex stiffness?
