How Multiple Sclerosis Affects the Feet

Multiple sclerosis (MS) is a demyelinating disease of the central nervous system—the myelin sheaths protecting nerve fibers in the brain and spinal cord are damaged, disrupting neural signal transmission. While MS itself originates in the CNS, its effects on foot function are profound and often severely impact mobility and quality of life. Approximately 75% of people with MS develop significant lower extremity neurological symptoms.

The most common MS-related foot problem is foot drop—weakness or paralysis of the tibialis anterior and other dorsiflexor muscles that lift the foot during walking. In MS, foot drop results from demyelinating lesions affecting the corticospinal tract pathways controlling the lower extremity. Patients with MS foot drop cannot lift the foot during the swing phase of gait, resulting in tripping, scuffing, and fall risk. This is distinct from peripheral foot drop (caused by peroneal nerve injury) in that MS foot drop reflects upper motor neuron pathology.

Sensory changes in the feet are similarly common: numbness, tingling, burning dysesthesias, and Lhermitte’s sign (electrical sensations down the spine into the feet with neck flexion) reflect spinal cord involvement. Spasticity—muscle stiffness and involuntary spasms—affects the feet and ankles in many MS patients, causing equinus positioning (tiptoe stance), toe curling, and painful muscle cramps.

Podiatric Management of MS Foot Problems

Ankle-foot orthoses (AFOs) are the primary podiatric intervention for MS foot drop. AFOs are custom-fit plastic or carbon fiber braces that hold the foot in dorsiflexion during walking, preventing the toe scuffing and trips that cause falls. Carbon fiber leaf spring AFOs are preferred by many MS patients for their lighter weight and energy return during walking. Functional electrical stimulation (FES) devices like the Bioness L300 can stimulate the peroneal nerve to lift the foot during swing—an alternative to rigid AFOs for appropriate patients.

Custom orthotics address spasticity-related deformity in MS feet. Spasticity creates abnormal force vectors on the foot skeleton, causing progressive deformities including forefoot equinus, hallux valgus, and toe flexion contractures. Custom orthotics with appropriate posting and accommodation can reduce these deforming forces, slow progression, and maintain comfortable footwear fit as deformity develops. Toe spacers and padding reduce friction from crowded toes in spastic feet.

Skin and nail care requires special attention in MS patients with sensory loss. Reduced sensation means wounds, ingrown nails, and pressure ulcers may develop undetected. Regular podiatric monitoring—typically every 3-6 months—allows early detection and treatment of skin breakdown before it becomes complicated. MS patients should inspect feet daily and have a family member or home health aide assist if visual or tactile inspection is difficult.

Footwear Considerations for MS Patients

Footwear selection for MS patients balances multiple requirements: adequate width to accommodate spasticity-related deformities; sufficient depth to accommodate AFOs; firm, non-slip sole for stability; ease of donning and doffing (Velcro rather than laces for patients with upper extremity weakness or coordination problems); and lightweight construction to minimize fatigue in patients with lower extremity weakness.

Wide-toe-box athletic shoes or diabetic shoes typically accommodate AFOs better than standard footwear. New Balance, Brooks, and ASICS make styles with generous volume appropriate for AFO use. Avoid slip-on shoes, high heels, and any footwear with inadequate ankle support for patients with significant foot drop or spasticity.

Fatigue management intersects with footwear: heavier shoes increase the energy cost of walking in patients already dealing with MS fatigue. Lightweight construction (under 10 oz per shoe) is meaningful for MS patients who walk significant distances. Rocker-sole shoes can reduce energy expenditure by offloading the push-off phase—beneficial for MS patients with lower extremity weakness.
