Big Toe Motion

A flexible toe box is generally useful because big toe extension matters during late gait. Great toe extension should reach about 70 degrees. Big-toe extension limitations are used to show that the same visible movement restriction can arise from different mechanics. In calcaneal eversion, forefoot flattening pushes the first ray into dorsiflexion and biases the big toe toward flexion. In calcaneal inversion, big-toe extension may be limited either because the first ray remains dorsiflexed or because the big toe is already near end-range extension. Great toe extension limitations can come from pelvis, ribcage, ankle, and calcaneus influences rather than only from the toe. In calcaneal eversion, the plantar tissues may be held short, limiting the ability to extend the big toe. If the big toe cannot extend, the shoe should avoid demanding motion the person lacks. After proximal influences and calcaneus position are addressed, ankle dorsiflexion is prioritized before forcing big toe extension. Direct big toe extension work should come after proximal influences, calcaneus position, and ankle dorsiflexion have been addressed. A flexible toe box may be inappropriate for people with hall…
