A step above the original Pinnacle orthotics, you won't believe the amazing support you'll get with these! The new arch support design incorporates two features that make the Powerstep(TM) pinnacle max orthotic arch supports more supportive than any of the other Powerstep models. First is the formula used that will give more resistance to a collapsing (or over pronated) arch and therefore more support. The second is the squared heel design which will sit squarely in your shoes and will not roll to either side. Two cushioning layers. The top layer is made from HyPUR-cel(R) foam which is bouncy and soft. The bottom layer is a low density EVA foam that has great internal strength and a low compression set. This means it's firm rather than bouncy and maintains great shock absorption properties. Made of 100% textile materials. Spot clean with a mild detergent, do not immerse in water, air dry only.
