Abstract
An ankle brace designed to be worn under the shoe has a first bladder which is filled with the high viscosity gel resistant to rapid deformation to apply pressure to the ankle and conform to its shape to provide support to the ankle. A second bladder inflatable with air is juxtaposed the first bladder to provide a uniform compressive force upon the bladder filled with the gel. A canvas ankle brace holds a pair of air and gel bladders along each of its sidewalls and is wrapped about the lower extremity and snugly fit thereto. Once the brace is in position, air is introduced into the second bladder to press the first bladder against the ankle and to conform to the shape thereof. Broad elastic straps may be secured to the lower rear of the brace to extend over the front of the ankle and the instep in a cruciate configuration. The outer ends of the straps are secured to lines which extend through openings in the outer casing of the brace, and D-rings secured to the ends of the lines permit the tensioning of the elastic straps by threading shoe laces through the rings and tightening the laces.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
