My knees are now two months on from starting on Apos shoes and I can safely say they have made them so much better. I wont say cure who knows what might happen but I do not have any night pain I can walk up and down stairs with no pain. Last week I ran up two lots of stairs at the railway station. I can use a static bike, treadmill and cross trainer with no or little symptoms despite a medial meniscal tear in one knee and osteoarthritis in the other for which the only prospect was a total knee replcement when the pain got too bad. The shoes can also help hips ankles and bad backs. I wear them around the house for two hours a day. I could also wear them outside for walking but my normal dog walk is quite an uneven and hilly walk so I prefer to keep them clean for indoor use. I find it astonishing that something so simple could help so much without surgery or drugs.
