The PRP Pressure Relief Diabetic Insert from Ovation Medical is a breakthrough in diabetic pressure relief for the foot. It is a diabetic sole insert that is made up of many pressure relieving pegs. Each peg is made up of 3 layers. The top layer is the contact layer for contact with the foot. The 2nd layer just below the contact layer is the stability layer. The 3rd Layer, underlying the top 2 layers, is the compression layer. The pegs are removable to adjust for ulcers and pressure points.
