walking boots-- which are good?

I didn't connect it with the boots at first, but when I doffed the boots the knee problem very quickly disappeared. It's possible my gait in the above ankle boots was a factor, but I'm guessing it was mostly the swinging weight of the boots. The knee is basically a hinge. It can move through nearly 180 degrees, but only in a single plane. The ankle has a more limited range of motion but is also more tolerant of movement in different planes, especially in combination with the feet -- there's a whole collection of joints down there. What sometimes happens when you restrict the mobility of the ankles and feet is that any sort of lateral or twisting movements that these would normally handle are transferred to the knees, which don't appreciate them. For an excruciatingly detailed discussion of this, see http://www.tmuscle.com/portal_includ...-training.html Then again, it could just be the swinging weight. It's very complicated. I attributed the pain to the weight because it was most painful at the top of the swing. As if my gait and muscles propelling the boot weight upward were more than my knee joint liked in reversing that momentum. Perhaps hyper-extending the joint. I don't reject the other suggestions here about the boots changing my gait, though my gait seemed entirely natural and fluid to me. It does make sense that the boot binding of the ankles and their weight did adjust my gait. Some years later I had pain in both knees, and had x-rays, then a cat scan, then a session of physical therapy. The x-ray guy suggested possible arthritis, the cat scan analyst found nothing wrong. Mind you, the pain wasn't debilitating until I walked a bit, but painful enough at other times that I wanted to address it and remove it I did the therapy exercises at home for a week or so with no result. Then my wife came home from the rummage store with an ottoman, and said, "Get your damn legs off that table, and use this." Some months earlier I set up my computer paraphernalia on a large, sturdy table, and began working from a reclining easy chair with the keyboard on my lap, and my feet extended to the table, heels or heel, depending if my legs were crossed, carrying the weight of my legs. This was the most comfortable work position I've ever found, giving total back support, and I never suffered any knee pain sitting like this. But my knees were suspended in mid-air, and were hyper-extending. I did as my wife demanded, and all knee pain was gone in a few days. No doctor has asked about this seating position, and I never thought to mention it. Just one of the countless ways a wife is handy. --Vic |
