If you have what is called "Plantar Faciatis" then this will apply to you:
After you sit for awhile, or after sleeping , and you stand and put weight on your feet, they will hurt. As you walk , they "warm up" and hurt less for a bit, but then as the day wears on they will start to hurt more.
If you have PF, as I do, then walking barefoot will not be a good thing, . . Not until the problem is well in remission.
If you wear soft shoes like flip flops, stop for a while. Look for shoes with really solid, hard shoes (like a steel shanked boot) with a "rocker" shape built into them.
For around the house, wear either Dansko clogs or get a kind of slipper that has a good arch built into it, such as a Haflinger (a German brand that have nice support. They feel like heaven).
When you are out working, you need to wear good shoes. Sorry, if it means taking the time to change from walking boots to riding boots, then you will need to do this. For walking around the barn and on this uneven ground, get a pair of really firm soled hiking boots. Or, the kind of heavy work boots a farrier might wear. Put insoles in them. Don't use cheap Spenco ones. Use Superfeet. OR, go to a Podiatrist and get custom ones made.
All this costs money, but pain in your feet is at the absolute foundation of wellbeing, and this is worth a LOT , isn't it?
