Dynamic orthosis for the ankle and foot joint designed by Orliman. Made of thermoplastic in two pieces. A low density covering the back of the leg and plantar surface. A higher density one designed to provide more rigid support and optimize positioning and alignment. It covers the perimeter of the midfoot so that there can be a correct adaptation and proper containment of tissues. Recommended in cases where there is knee hyperextension and lack of balance or coordination. Also, when there is evidence of weakness or excessive plantar flexion. The closure system has been designed in Velcro to prevent displacement and an optimal fit. Size 1 (short) has a height of 12.2cm with a foot length of 12.4cm. It is recommended to use the appropriate size.
