RTP Carbon Fiber Inserts are MADE IN USA. A TEXTURED surface on BOTH sides prevents slipping in shoe, Carbon fiber is used because of its light weight, stiffness, durability, allowing a very thin insert to stiffen the shoe protecting the foot. Not all injuries, pain levels, activity levels, or shoes are the same. 3 levels of stiffness for foot injuries: SEMI-RIGID stiff but flexible, RIGID stiffer but some flex, ARTHRITIC very stiff minimal flex. IF IN DOUBT GO DOWN TO MOST FLEXIBLE INSERT
SHOE MUST HAVE REMOVABLE INSOLE; Works best with big toe injuries that require added support in tighter fitting shoes as cleats and some casual /dress shoes without making the shoe too tight when the full insert isn't needed.
