"temperatures of 35 degrees celsius in the shade (95° Fahrenheit)" That is a cool day here this time of year lol. I agree that it matters where you decide to go barefoot. I spent time in Hawaii and the grass and and beach are fine to walk on and since it rains every day, even the sidewalks are pretty clean in many places. Here it is all thorns that are strong enough to puncture bike tires, 112 degree concrete, and large ants.
