Too cool! Easy to make and great for your feet. Foot sensation trails–the first time I came across anything like this was when I was living in Malaysia and they had a very cool path with varying sizes of stones along it. The point of the path was to be a reflexology stimulation to the soles of your feet and not so much for grounding or earthing, which has become a healing phenomenon of it’s own (more about earthing here). This is a great idea. I hope we will have a foot sensation path coming to a park near us this summer 🙂
