You may qualify if…

• Subjects must indicate that they currently have weakened ankles or knees and that they experience chronic discomfort after performing daily activities.
• Subjects must suffer from pain assessed on a 100 mm (10 cm) Visual Analog Scale (VAS) of ≥20 mm to ≤ 90 mm for subjects with either unstable ankle or unstable knee, at Visit 1 and 2.
• Subjects must be able to walk unaided by cane or walker.
• Subjects must not have a noticeable limp or other permanent ailment that interferes with normal gait.
• Subjects free of other types of health problems that, in the opinion of the Investigator, could influence their ability to participate.
• If subjects are taking pain medication (prescription or Over-the-counter (OTC)) for a chronic condition, they may continue that medication as long as they have been on a stable dose for at least 2 months, and agree to continue their regular dose and regimen for the duration of the study.
• Subjects must be willing to undergo a 1-week period without a brace and then willing to wear a brace for a 1-week period, that is: 8 ±2 hours a day for a minimum of 5 out of 7 days.

You may not qualify if…

• Subjects with an ankle or knee pain and instability which is due to a recent sprains, strains, or other non-reversible injury to the knee or ankle.
• Subjects who have diabetes, circulatory problems, open wounds, and lack of sensation in the ankles, knees, or feet or any problems that would make brace wear uncomfortable or inappropriate.
• Subjects who wear a physician-prescribed orthotic device, prescription shoes or back braces.
• Subjects who are undergoing traction or manipulative back adjustments or have had a traumatic injury to the lower extremity (deemed of non-overuse nature), which in the opinion of the examining Investigator would interfere with the study evaluations.
• Subjects whose condition requires surgery or other medical intervention or who have undergone foot back or knee surgery within the past 3 months or with any planned surgeries and/or invasive medical procedures during the course of the study.
• Subjects who are currently taking an opioid based pain medication or have taken such medication within 2 months prior to Visit 1.
• Subjects who are taking any chronic pain medication (prescription or OTC) for at least 2 months, who do not agree to continue taking it at the same dose and regimen throughout the study.
• Subjects who have severely painful bunions, warts, corns and/or calluses, severely overlapping toes or lesions on the bottom of their foot.
• Subjects who have sensitivities or allergies to plastics or adhesives.
