Abstract: An ankle and foot support brace is described which is made of three components; an inner slide-on sleeve, a plantar cushion, and an outer mono-unit strapping system. The sleeve is very thin at a thickness of about one-thirty-seconds of an inch. The sleeve is made of a stretchable resilient material such as Spandex. The plantar cushion may be removable or permanently attached to the brace and can further be personalized in its makeup to form a therapeutic orthotic. The mono-unit strapping system is also thin, made of strong resilient composite, and having a thickness commensurate with the sleeve and includes two heel lock straps, two stirrup straps, and two figure eight straps. The lateral stirrup includes two locking straps.
