Physical Therapy and My Knee

2 weeks of therapy. I might be seeing some improvement. But Im going out to buy a new pair of shoes today. I'm beginning to think maybe that might be part of the problem. If its the shoes it will be the most expensive pair of shoes ever. Ill be so mad. I hope its not and to be honest I don't think shoes are the sole reason. Besides I know my knee is weak and Im sure the physical therapy is helping with that.
