After you barefoot an especially hot or cold surface, the tingling of the tiny nerves in the soles is such a unique barefoot pleasure! mmmmmmmmmmmmmmmmmmm
Ya. I did a 5 mile hike this weekend. By the end, the ground was getting pretty hot from the sun. Feet felt great afterwards.
Some of the trails around here use various size gravel/stone to combat erosion. If it's a uniform layer I can walk over it pretty easily as they tend to use rounded/smooth type rock. T he worst is randomly scattered pieces. Accidentally stepping on a single big piece with heel or instep is painful. I had to look up rhyolite - looks sharp edged and nasty. Yuck
