My experience won't apply to most, but there is an alternative herein for a strategy I read elsewhere ...
I have four issues related to my feet. First, I have what the doctors call "a progressive deformation of the bones" in my feet. The way the bones fit together has become distorted, and since it is "progressive," it gets worse as I age. I first started having problems when I was about 19 and got a job where I was constantly on my feet. It got to the point that, 15 minutes after I'd stat my daily shift, I couldn't flex my feet.
Second (and related to the first), I have ridiculous arches. They're so high that I tend to walk on the outside edges of my feet. I wear custom orthotics that work to control this, and they work wonders -- to a point. For some reason, my right foot is much worse than my left.
Third, about 18 years ago I had a freak accident that essentially shredded the cartilege in my left knee. This still tends to hurt when I don't get enough sleep. There is bone-on-bone contact in the knee, and one day I may need a knee replacement. I have to be careful on stairs and take it slow -- if it is really quiet, you can hear my knee click and pop as I flex the joint! Freaky!
Fourth, a couple of years ago I was in a head-on collision at about 50 mph with a drunk driver. In addition to a broken rib, lacerated spleen, and deep bruises galore, I had a broken bone in the bottom of my left foot. It is healed, but apparently the pain is here to stay.
As a result of all this, every step I take is painful. The pain isn't excrutiating. However, imagine a very mild pinch. Not that big a deal, right? Now imagine that pinch being held every waking hour of every day. This has been true for the last 20 years, give or take, but these more recent events and the progressive nature of the bone problem means it is getting worse. Because of the orthotics I wear, I rarely go barefoot, even around the house. I have one pair of shoes I wear everyday. I have a pair of dress shoes I can wear when I need them, as well as some heavy boots, but I change them as soon as I can. Sandals, deck shoes, Crocs and other such things are completely out. On top of all that, I have to get very wide shoes for my everyday wear -- New Balance shoes that cost about $100 a pair.
So, all that to say this: I read in another thread someone say that they take two pairs of shoes to the parks and change in the middle of the day. The different shoes fit well but in different ways, which reduces stress on any one point of the feet. Well, I can't do that (at least not without buying two pairs of the same shoes), so I often bring a second pair of socks with me to the park. If I'm going to be there all day, I'll try to change socks in mid-afternoon. The fresh socks seem to really help refresh my feet.
