Re: Dumb queston...Re: Love it!...Re: Barefoot Walking, Foot Reflexology & Hydrotherapy Combined (Synergistic effect? I think so)
It might matter to you, otherwise I don't think so.
Personally, I used to walk barefoot on medium sized driveway slag when I had to; and I've run barefoot on the small cinders like a high school track (this was in the park). The gravel we had in our yard was the medium sized mixed-lot river gravel, smooth and mostly brown.
Notice that in
Dr. Schulze 's piece about "Why Natural Healing Doesn't Work" (the way some others practice it), he mentioned one practitioner doing foot reflexology on someone so hard that the patient was screaming in agony. And that was necessary (or deemed necessary) to heal them. So as long as the gravel isn't sharp enough to cut you, it shouldn't hurt you. BUT, that smooth river gravel was pretty darn nice.
Some Chinese company makes mats and rubber paths with half sections of stones glued to it. Just getting a cubic yard of the stuff and have it dumped in a prepared spot might be better! That's what I'm going to do here. With a few drain tile buried below, maybe. Eight-foot diameter, I think.
And before I forget, if you ever had one of those Bangkok Taxi Driver's Seat Pads, made from hundreds of litle round wooden beads strung together with monofiliment line... those things always end up coming unstrung. You can put the beads in a plastic tub or wooden tray and get a great inside-the-house foot reflexology massage that way. River stones would also work, but the wooden beads are clean.
