The Powerstep ProTech Custom Post from Stable Step allows for quick and simple adjustments with heel posts or heel lifts to easily create a customized orthotic product. Each full length polypropylene orthotic shell with an EVA base, Poron top layer, and antimicrobial top cover; shells come in seven sizes (mens 4-14½, womens 6-15½). Polypropylene posts or lifts snap into the base of the shell, making it no longer necessary to grind, form, or attach additional heel pads or wedges. Snap-on posts come in neutral (0°), 2°, and 4° for either varus or valgus application. Snap-on heel lifts come in ⅛” and ¼” heights.
