When I used to run, I wore NB Fresh Foam 1080. I still wear them, although no more running (hip soreness). Excellent cushioning and comfortable/breathable upper.

Agree with "knowing how to run". I changed my running style from heel striker (caused hip soreness) to mid-forefoot striker but it was too late. Heel striking does not use the calf as a shock absorber and the impact goes straight into the hip joint. The style change improved comfort but I think my hips were too far gone for the style change to extend my running career. Apologies if tmi.
