The long big-toe flexor

What it does

The flexor hallucis longus runs down the back of the fibula, behind the inner ankle and under the foot to the tip of the big toe. It bends the big toe and gives the strong final push-off when you walk, run or rise onto your toes.

Why it matters

The push from your big toe launches each step, and this muscle provides it. Stiffness here can change how you walk and lead to pain elsewhere.
