Powerstep ProTech Custom Post Orthotic Support is a unique, patented orthotic design specifically for medical professionals using quality materials and designs. The patented shell design allows for the quick and simple adjustments of either heel posts or heel lifts to easily create a customized product for your patients. Simply snap the posts or heel heights into the base of the shell; it is no longer necessary to grind, form or attach additional heel pads or wedges. The snap-on heel stays securely in place for a comfortable fit and improved performance. Includes snap-on rear foot postings for varus or valgus application (0°, 2°, or 4°) and snap-on heel lifts in heights of 1/8” and 1/4”.
