Fit and Shoe Setup Matter
Proper sizing, compatible footwear, adequate shoe volume, and professional adjustment can make a major difference in comfort and performance. Measure carefully and review our fit guide before ordering.
AFO Dynamic 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 calf height and shoe size overlap or conflict, consult a qualified orthotist rather than automatically sizing up or down.
- Have a qualified orthotist assess footplate fit and carry out any allowed modifications under Ossur’s fitting instructions. Do not modify carbon fiber yourself or size up just to accommodate footwear.

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 Dynamic size?
Measure calf height from the thickest part of the calf straight down to the floor, then confirm the corresponding US shoe-size range. Calf height is not calf circumference. Ask a qualified orthotist for help if measurements overlap or disagree.
What if the foot plate is too long for my shoe?
A qualified orthotist should assess and perform any footplate adjustment according to Ossur's instructions. Do not trim or grind carbon fiber yourself, and do not automatically choose a larger brace simply to fit your shoe.
Can the AFO Dynamic handle mild knee instability?
Yes. Unlike the AFO Light, the AFO Dynamic provides medial-lateral stability at mid-stance, making it suitable for patients with mild knee instability in addition to drop foot. The full-length toe lever and tapered carbon heel also help reduce compensatory movements that can stress the knee and hip during gait.
When should I replace the straps and padding?
Replace straps and padding when fasteners lose grip, padding compresses or becomes damaged, straps fray, or the brace no longer fits securely. There is no fixed annual replacement schedule. AFO Dynamic Accessory Kit
