Fantastic boot! Super comfortable and love the air pump for additional ankle support. I actually put 20k steps on it the other day doing yard work and felt just fine. Highly recommended!

Description
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 — this is where the velcro strap will sit and hold the brace in place. Using a flexible tape measure, measure from that thickest 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 — this is where the velcro holds the brace, so calf height (not circumference) is what 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. Any orthotic company — such as Hanger Orthotics and Prosthetics — can trim your AFO foot plate to the correct size. Do not buy a larger size just to accommodate your shoe.

Frequently Asked Questions
What is foot drop and what causes it?
Foot drop (also called drop foot) is the inability to lift the front part of the foot, causing it to drag on the floor during walking. It is not a disease itself — it is a sign of an underlying neurological, muscular, or anatomical problem. 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. Foot drop may be temporary or permanent depending on the underlying cause.
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 — raising the thigh higher than normal to clear the foot — and foot slap when the foot hits the ground. In some cases, the skin on the top of the foot and toes may feel numb. 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. This is where the velcro strap wraps around and holds the brace in place. Measure from that thickest point straight down to the floor. Match this measurement to the size chart above. Your shoe size is used as a secondary confirmation. Do not measure calf circumference — it is not used for sizing this brace.
What if the foot plate is too long for my shoe?
Do not buy a larger size to accommodate your shoe. Instead, have the foot plate professionally trimmed. Any orthotic company — such as Hanger Orthotics and Prosthetics — can trim your AFO foot plate to the correct size. This is a routine procedure that preserves the structural integrity of the carbon fiber and ensures a proper fit inside your shoe.
What's the difference between the AFO Light and the AFO Dynamic?
The AFO Light features anterior (front) mounting and is ideal for mild to moderate drop foot in patients up to 220 lbs. The AFO Dynamic has side-mounted support for better comfort and pressure distribution, supports up to 265 lbs, includes a full-length toe lever and tapered carbon heel for enhanced energy return, and is less visible in shoes. Many patients prefer the AFO Dynamic for its superior fit and performance across a wider range of activity levels. 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 that replacement is needed include: Velcro no longer grips securely, padding is compressed or thinned, straps are frayed or stretched, or the brace feels loose even when fully tightened. The AFO Light Accessory Kit (O-122101) includes all replacement soft goods.
