Abstract

A foot splint for the prevention and rehabilitation of plantar fasciitis by maintaining a wearer'"'"'s foot and, hence, his plantar fascia, in a preselected amount of dorsiflexion. The foot splint includes a footplate for supporting the wearer'"'"'s foot, a lateral strut extending along the lower leg of the wearer and having a strap for releaseably attaching the strut to the wearer'"'"'s leg, and a wrap for wrapping around the foot of the wearer. A soft insole may be provided to cushion the wearer'"'"'s foot from the footplate. The wrap, insole and footplate provide a comfortable “slipper-like” feel for the wearer. Moreover, the foot splint is particularly suited for use during sleep since it is light-weight and open configuration allows for the wearer to move unimpeded between sleep positions, resulting in a more restful sleep. Moreover, the lateral placement of the strut keeps the rigid portions of the foot splint from inadvertently abrading, striking, or otherwise interfering with the wearer'"'"'s other leg.
