I can believe it with the light colored asphalt which aren't much white, but 
there is a BIG difference with white concrete tile. My feet aren't the 
toughest, but in mid summer I can walk barefoot on a white concrete roof, but 
can't go 20 minutes in big nobbly hiking shoes on a black one. Feet feeling 
like they're baking in an oven is a very uncomfortable, unnatural feeling. I go 
for only medium-rare.
