Foot

adductor hallucis

a-DUK-tor hal-OO-sis

Inner foot muscle adducts the big toe, stabilizing the transverse arch during toe-off. Prevents hallux valgus and aids propulsion. Important for barefoot training enthusiasts.

Common Pain & Injury

Pain under ball of foot or big toe from ill-fitting shoes, metatarsalgia-like. See doc for bunion progression.

Anatomy & Function

Origin

Bases of 2nd-4th metatarsals and plantar ligaments (mid-foot bones).

Insertion

Lateral base of proximal phalanx of hallux (big toe inner base).

Actions

  • Adduction of great toe (pulling big toe inward)
  • Flexion of metatarsophalangeal joint (bending toe base)

Innervation

Lateral plantar nerve (S2-S3).

Related Foot Muscles

Abductor digiti minimi of left foot
This small muscle on the outer edge of the left foot spreads the little toe away from the others, aiding balance and push-off in gait. It's vital for foot arch stability during running or lateral movements. Runners and athletes appreciate its role in preventing foot pronation issues.
Abductor digiti minimi of right foot
This muscle runs along the outer arch of the right foot, abducting the little toe to support lateral stability and toe-off in walking. Essential for preventing supination injuries in trail running. It matters for overall foot mechanics in dynamic sports.
abductor hallucis
This medial foot muscle abducts and flexes the big toe, supporting the arch and propulsion in walking or sprinting. Key for preventing flat feet and plantar fasciitis. Runners target it for injury prevention and efficiency.
extensor hallucis brevis
The extensor hallucis brevis is a small muscle on the top of the foot that specifically extends the big toe (hallux). It works alongside other extensors to lift the toes during walking or running, preventing toes from dragging. For fitness enthusiasts, it's key for foot stability in activities like sprinting or plyometrics.
First lumbrical of left foot
The first lumbrical of the left foot is a small worm-like muscle that flexes the big toe's base and extends its tip, stabilizing during gait. It fine-tunes toe position for balance in yoga or barefoot training. Key for foot intrinsic strength.
First lumbrical of right foot
The first lumbrical of the right foot flexes the big toe's proximal joint and extends the distal one for precise foot control. Essential for push-off in unilateral sports like kicking. Builds foot dexterity for minimalist shoe training.
flexor accessorius
Flexor accessorius (quadratus plantae) is a flat muscle in the sole of the foot that assists flexing the lateral toes. It aligns toe flexors for even toe curl in gripping surfaces. Useful for climbers and martial artists needing foot grip.
Flexor digiti minimi brevis of left foot
This small muscle in the left foot's sole flexes the pinky toe at its base. It aids toe grip for balance on uneven terrain. Relevant for barefoot runners enhancing foot intrinsics.
