Ossur Carbon Fiber AFO Light Drop Foot Brace
The Össur Carbon Fiber AFO Light is the #1 doctor-recommended carbon fiber AFO that provides excellent support where needed, eliminating unnecessary bulk while delivering a cosmetically appealing, low-profile design. Utilizing Flex-Foot technology and the energy-storing properties of carbon fiber, the AFO Light offers a strong and lightweight solution for people with mild to moderate drop foot.
Carbon Fiber Technology: Carbon fiber is an extraordinarily strong polymer material that is five times stronger than steel yet twice as stiff, while remaining extremely lightweight. The thin, strong crystalline filaments create a spring-like action that aids the foot in dynamic motion, providing energy return during walking.
⚠️ IMPORTANT: Proper Fit is Critical for Comfort & Effectiveness
Returns due to fit issues are common with AFO braces. Please take time to measure carefully and review our comprehensive fit guide before ordering.

💡 Customer Recommendation: Consider Upgrading
Many customers who purchase the AFO Light find they wish they had chosen the AFO Dynamic instead.
Why AFO Dynamic is Often Preferred:
-
Side-mounted support provides more comfortable fit and better pressure distribution
-
Higher weight capacity: 265 lbs vs. 220 lbs
-
Full-length toe lever for complete support during stance phase
-
Tapered carbon heel stores more energy for efficient walking
-
Less visible in shoes due to medial strut placement
-
Better for active lifestyles and varying degrees of drop foot
Össur AFO Light Selection & Measurement Chart
How to Measure for the Correct Size
Sizing is based on two measurements: Calf Height and Shoe Size. Do not measure circumference — the velcro strap wraps around the thickest point of your calf, so what matters is the height of that point from the floor, not how wide your calf is.
-
Calf Height (Primary): Stand upright. Find the thickest point of your calf. Measure from that point straight down to the floor. Match this measurement to the chart below.
-
Shoe Size (Secondary): Use your regular US shoe size to confirm the correct size and foot plate length.
📏 Sizing & Fit Tips:
- Measure your calf at its thickest point — calf height (not circumference) determines your size.
- If you are between sizes, choose the smaller size for a more secure fit.
- If the foot plate is slightly too long for your shoe, it can be professionally trimmed by any orthotic company such as Hanger Orthotics and Prosthetics.

Frequently Asked Questions
What is foot drop and what causes it?
Foot drop is the inability to lift the front part of the foot, causing it to drag on the floor during walking. Common causes include compression or injury to the peroneal nerve, stroke, multiple sclerosis, ALS, Charcot-Marie-Tooth disease, or complications from hip or knee replacement surgery.
What are the symptoms of foot drop?
Foot drop makes it difficult to lift the front part of your foot, causing it to drag on the floor. This often results in a steppage gait and foot slap when the foot hits the ground. Patients may also trip or stumble more frequently on uneven surfaces.
How do I measure for the correct AFO Light size?
Sizing is based on calf height — not circumference. Stand upright and find the thickest point of your calf. Measure from that point straight down to the floor. Match this measurement to the size chart above. Your shoe size is used as a secondary confirmation.
What if the foot plate is too long for my shoe?
Do not buy a larger size to accommodate your shoe. Have the foot plate professionally trimmed by an orthotic company such as Hanger Orthotics and Prosthetics. This is a routine procedure that preserves the structural integrity of the carbon fiber.
What's the difference between the AFO Light and the AFO Dynamic?
The AFO Light features anterior mounting and is ideal for mild to moderate drop foot in patients up to 220 lbs. The AFO Dynamic has side-mounted support, supports up to 265 lbs, includes a full-length toe lever and tapered carbon heel, and is less visible in shoes. Compare AFO Dynamic here →
When should I replace the straps and padding on my AFO?
With daily use, soft goods typically need replacement approximately once per year. Signs include Velcro no longer gripping securely, padding compressed or thinned, or straps frayed or stretched. The AFO Light Accessory Kit (O-122101) includes all replacement soft goods.
