That's my problem. I commission new power plants, and I've had a bunch of sites recently that involved a lot of walking on paved or gravel surfaces. Especially the site I've been working in Canada. I think the problem really flared up when I was there before the end of the year and it was icy. I wore these grabber/cleat things that slip over your boot to give you traction on ice. Walking with the dang things was like having something poking you right in the bottom of the arch. I've been bringing 2 different sets of boots on every job since and keep swapping between them to try to get relief. I bought some of the Dr. Scholls, Plantar Fasciitis inserts and I'll give them a try. I bought some expensive "Sole" branded inserts, and they did nothing for me.
I wore that brace last night, not perfect, but it seemed to work. This morning, I stretched and went straight into my tennis shoes. I'm trying to "tread lightly" (see what I did there?

), and try to get on top of this before I go back to that site next week.
Every time I think I'm seeing improvement; I have a set back. It seems like all it takes is 10 steps in the wrong shoes, not properly stretched, wrong surface etc.etc. and you're screwed again.
