I completely understand. When I was 20 my feet got caught in the tow rope and I was dragged behind a boat. They thought that we both just fell, but I got caught was caught. A scary thing, believe me. Ever since then, my standing stamina is poor. Walking is better, but even that isn't what it could be. I was an old lady before I was old! LOL
I've swallowed my pride and I now wear Crocs all the time. They help - not completely, but enough.
You definitely make compromises. For me, since my foot healed crooked, it's difficult to skate. The one foot keeps wanting to go in circles.
Walking long distances is not as hard for me as standing for long periods.
