The device features dual hinges made of stainless steel, and a patented strap system that provides effective, comfortable varus/valgus support. It fits easily in standard shoes, weighs only 458 g, and is available in four sizes—Small, Medium, Large, and Extra Large—for both left and right feet.   Step-On AFO 200 DH is part of the "STEP-ON AFO" family of products which:
Feature slimline hinge and foot plate design and come with ¾ length foot plates, allowing them to fit easily in different everyday and formal shoes. They can also be combined with foot orthoses (insoles). The tibial shell is covered with a lining, which can be removed hand washed and air dried. All hook-and-loop straps are sufficiently long and can be cut to the appropriate length during fitting. Furthermore, the straps are fitted with foam pads, ensuring comfort and enhancing skin integrity. Both the tibial shell and foot plate are made of high-quality polypropylene. They can be easily formed to shape using mild heat treatment and they can be trimmed back by an orthotist/technician.

The hinges are protected by a neoprene sleeve, in order to avoid contamination with debris during daily use. Furthermore, the hinge system can be fully disassembled for cleaning and servicing, while a full list of spare parts is provided, to ensure a prolonged lifetime for all Step-On AFOs.
