What is the Flexor Hallucis Brevis?
The flexor hallucis brevis is a small muscle in the bottom of your foot that helps you bend your big toe. It sits in the arch area, closer to the front half of the foot, and it works at the big toe joint where the toe meets the foot. Think of it as part of the “push-off team” that helps you drive into the ground when you walk, run, jump, or do calf raises.
