I'm not sure if this will work. This is a Richie Brace, just like the one I got today. It's a custom orthopedic ankle brace which, the technician told me, was invented for my problem. My problem has a long name with initials - PTT - maybe post-tibial tendonitis or something like that. It's basically what happens when you get old and have had no arch in your foot and weak ankles all your life. The ankle bones are misaligned and instead of your leg to foot being perpendicular, you wind up at a bit of slant, which makes walking painful, difficult, and very tiring.
I had instant relief. The test will be when I go back to work on Monday and work a 12-hour shift in a factory with cement under the linoleum (heavy equipment - it's a wafer fabrication plant; we make magnetic heads for disc drives for computers).
