Some background: The actual temperature of a surface depends on a number of factors such as how dark or how efficiently the surface absorbs the sun's UV and IR radiation. A surface that appears very dark to the eye may not be as dark in the infrared. Also, the surface temperature can be affected by how much the soil below conducts heat away from the top layer. The better the conduction, the lower the surface temperature. Therefore, you can't look for what you might hope is a cooler surface based on its color.In general, for me, most asphalt is either pleasantly warm or at or at least tolerably hot unless the ambient air temperature is 90F or over and it's mostly sunny. In such cases, there isn't much you can do.

On particularly hot days, I will go from shade patch to shade patch, and hang out until the burning subsides before continuing. One trick I've learned is that if you walk briskly, then the time your foot is in the air is enough to dissipate a lot of the heat absorbed during the previous step. Also, if you concentrate on the foot that's in the air, you will be focusing on where the heat is dissipating, not where it is accumulating. This gives you a psychological edge.Note: Prolonged exposure to hot surfaces can cause burns and blistering; pain is an indicator that tissue damage is not far behind. However, some barefooters report that, through gradual acclimation, one can greatly increase one's resistance to hot surfaces.
Tip: When you cross at intersections, the white stop-lines are cooler; you can walk on those.
