Patient Guide to Ankle-Foot Orthoses (AFOs): Uses, Wear, and Care
An ankle-foot orthosis (AFO) is an external support designed to stabilize the lower limb, correct alignment, and compensate for muscle weakness such as foot drop. This guide outlines how AFOs function, proper donning techniques, skin monitoring, and daily maintenance for safe mobility.
Quick Summary
An AFO stabilizes the ankle and controls foot position to improve walking safety, requiring proper footwear, a gradual break-in period, and vigilant skin checks.

Step-by-Step Guide
Understand the Clinical Purpose of Your AFO
AFOs are commonly prescribed for neuromuscular and musculoskeletal conditions such as stroke, multiple sclerosis, cerebral palsy, peripheral neuropathy, and peroneal nerve injury resulting in foot drop. The brace holds your foot at an optimal angle (typically 90 degrees) to prevent your toes from catching during the swing phase of walking and to provide medial-lateral ankle stability during stance. Knowing whether your brace is designed to be rigid, articulating (hinged), or dynamic helps you anticipate how it will guide your walking pattern.
Prepare Your Leg with a Proper Interface Sock
Always put on a clean, dry, seamless sock that extends higher than the top edge of the orthosis before applying the brace. Choose moisture-wicking fabrics like cotton blends or technical synthetics rather than heavy wool or textured knits that can create pressure ridges. Smooth out any wrinkles over the heel, shin, and ankle bone before placing the brace against your skin.
Important: Never wear an AFO directly against bare skin, as friction and trapped perspiration significantly increase the risk of skin tears and blistering.
Seat the Heel and Fasten Straps Sequentially
Sit comfortably with your knee bent at a 90-degree angle and slide your foot into the orthosis, ensuring your heel rests firmly against the bottom and back wall of the brace. Fasten the ankle strap (instep strap) first, as this anchors the hindfoot securely into the heel cup and prevents slippage. Next, secure the calf strap and any forefoot straps snugly enough to prevent movement without restricting arterial or venous blood flow.
Important: Ensure the heel does not lift off the base of the brace when tightening; a poorly seated heel creates abnormal pressure points and compromises gait control.
Pair with Appropriate, Supportive Footwear
Slide the braced foot into a supportive shoe featuring a removable factory insole, a wide toe box, and an adjustable closure mechanism like laces or Velcro. The shoe should have a low, stable heel, as varying heel heights tilt the brace forward or backward, altering knee biomechanics and increasing fall risk. You may need a shoe that is a half-size larger or wider than your standard size to accommodate the brace profile.
Adhere to a Gradual Break-In Schedule
Unless your orthotist directs otherwise, begin by wearing the brace for 1 to 2 hours on the first day, preferably during low-demand indoor activities. Gradually increase wear time by 1 to 2 hours each subsequent day over a one- to two-week period until you reach full-day use. This progressive adaptation allows your soft tissues and bony prominences to build tolerance to new pressure distribution patterns.
Important: Do not rush into full-time wear or high-impact walking immediately, as premature prolonged use is the leading cause of brace-induced pressure ulcers.
Perform Routine Post-Wear Skin Assessments
Remove your shoe, brace, and sock immediately after each wearing session to inspect the skin under bright lighting. Pay close attention to high-pressure zones, including the bony prominence of the inner and outer ankle (malleoli), the navicular bone on the inner arch, and the front of the shin. Mild pinkness that fades completely within 20 to 30 minutes of brace removal is expected adaptation.
Important: Contact your orthotist promptly if redness persists longer than 30 minutes, or if you detect blisters, bruising, skin breakdown, or numbness.
Clean and Maintain the Device Daily
Wipe the interior and exterior plastic or composite surfaces daily using a damp cloth and mild, antibacterial soap, then wipe dry with a towel. Allow the orthosis to air dry completely at room temperature away from direct heat sources such as radiators or hair dryers, which can warp molded thermoplastics. Regularly inspect hook-and-loop straps, rivets, and any mechanical hinge joints for wear, fraying, or loose hardware.
