The Powerstep ProTech Custom Post full-length orthotic insert is designed specifically as a customizable option for those different types of pedorthic conditions. The patented shell design allows for quick, simple adjustments of the included heel lift units or varus and valgus heel wedge units to easily create a customized orthotic product. The posts and heel heights easily snap into the base of the shell and keep it secured in place. It includes a double-layered shock-absorbing EVA foam cushioning. These orthotics are not available online and are found only at Lamey Wellehan locations staffed by Pedorthic associates. Visit your local Lamey Wellehan store for details and fitting.
