Good Idea, Poor result
"I really wanted to like these insoles, the concept of being able to add a carbon plate and a little more foam to a trainer thus making it a super trainer is a great idea. however it doesn't work with this product. the heal area is much too wide and can not be trimmed. the carbon plate adds stiffness without responsiveness. Super shoes and trainers work becuase the plate in sandwiched or inside the layer of foam. if the pate in in the insole it can not work with the foam. also most trainers where you would add this insole too use a foam thats already stable, not needing the pate for added stability like a race day shoe with a softer bouncier foam. Overall not my favorite and would recommend spending the money just to put toward a true super shoe."
