Foot pain and foot weakness, specifically weakness in the intrinsic muscles of the foot can cause many issues. Due to the small intrinsic foot muscle size, these muscles of the foot are commonly forgotten when it comes to strengthening. This post will cover the 7 best abductor digiti minimi foot exercises.
It is important to note that there are actually two abductor digiti minimi muscles in your body. One is in the hand and the other which this post will be discussing is in the foot. Although these two muscles share the same name they have significant differences.
Abductor Digiti Minimi Foot Pain
Abductor digiti minimi foot pain is pain at the bottom of the lateral or outside of the foot. This pain is typically near the pinky or 5th metatarsal and the symptoms may be very similar to that of a 5th met fracture. It is important to see a doctor to rule out any fractures.
Anatomy
Before we can dive into the best exercises for the abductor digiti minimi pedis we must first understand the anatomy of the foot muscles. The muscles we will be focusing on are the muscles of the lower leg and foot, specifically the foot intrinsics, extrinsic muscles and most importantly the abductor digiti minimi of the foot muscle.
- Abductor Hallucis: This abductor hallucis is one of the superficial plantar muscles of the foot which runs along the inside of the foot and big toe
- Flexor Digitorum Brevis: The flexor digotorum brevis muscle is part of the plantar muscles and is responsible for flexing the lateral 4 toes at the metatarsophalangeal joint. In other words this muscle bends all of the toes except for the big toe at the middle joint.
- Quadratus Plantae: The quadratus plantae is a plantar foot muscle that is responsible for flexing the 4 lateral toes and for assisting with walking by shortening the flexor digotorum longs muscles when the foot is in plantar flexion.
- Extensor Digitorum Brevis: The extensor digitorum brevis is an intrinsic muscle of the dorsal aspect of the foot. It is responsible for extending the 2nd, 3rd and 4th toes.
- Flexor Hallucis Brevis: The flexor hallucis brevis is the shorter muscle of flexor hallucis muscles. It works with the flexor hallucis longs muscle to bend or flex the big toe.
- Abductor Digiti Minimi Muscle: The abducor digiti minimi foot muscle is the most important muscle of the foot this post will be discussing. This is a small muscle of the foot and is one of the intrinsic muscles of the foot.
- Origin and Insertion:
- This muscle originates on the calcaneal and inserts on the plantar aponeurosis and runs along the lateral aspect of the foot.
- Nerve Supply
- Lateral Plantar Nerve
- Origin and Insertion:
Abductor Digiti Minimi Foot Function
The function of the abductor digiti minimi is to abduct the 5th toe or pinky toe and support the longitudinal arch during walking and running. Abduction of the pinky toe is the movement of the pinky toe laterally away from the other small toes.
Abductor Digiti Minimi Foot Nerve Supply
The nerve supply for the abductor digiti minimi foot muscle is the lateral plantar nerve.
Abductor Digiti Minimi (Foot Pain Cause)
Abdcutor digiti minimi foot pain can be caused by poor gait mechanics such as walking on the outer part of your foot, walking on hard surfaces and poor footwear. Typically abductor digiti minimi foot pain is caused by a combination of repetitive motions and poor mechanics over time.
It is important to note that often a 5th met or pinky toe fracture can feel like abductor digiti minimi foot pain. If you are feeling this pain you should go to your doctor so that they can rule out a fracture and avoid any further injury.
Abductor Digiti Minimi Foot Injury Symptoms
- Pain on lateral foot along 5th metatarsal (pain on outside of foot along pinky toe)

Common Problems Associated With Abductor Digiti Minimi Foot Pain
- Plantar Fasciitis
- Plantar fasciitis is when the plantar fascia, which is the connective tissue at the bottom of the foot that supports the arch of the foot becomes inflamed.
- Calcaneal Spur
- A calcaneal spur is a bony projection from the calcaneus or heel bone. This will often feel like heel pain.
