any one have experience with spd cleat wedges. with my orthotics from my podiatrist, adjusting my cleats ive got my right knee to were it dosnt bother me,but my left knee gives me some fits. from what i can tell my left out side of my foot may need to rotate up some. ive read that the spd wedges since are plastic like to let cleat slide around but work good with the other 3 and for 4 screw models. i would get a road cleat but havent found a shoe that fits right. thanks jason
