have used lewedge since it was called big meats. i assume you have knee pain as i did that apparently was from my feet canting inward. before you use them, try and get an accurate measurement of both legs to make sure you have no leg length issues. if one is longer than the other you may need to add a few extra wedges on the short side to compensate a little. add wedges in small increments like 2 wedges each side at a time. one wedge at a time is too small of an increment imho.
