There was a write up in the August issue of Backpacker called "how to walk". It discussed the correct way your stride should develop and end. Along w/ torso posture and uphill/downhill strides. Its an informative group of articles. They also discussed the advantages of the whole barefoot revolution. I truly never realized how aware I need to be of heel strike, toe off, over-stride etc. Walking has now become a mental game to correct my years of just putting one foot in front of the other. Something so easy as rotating your pelvis in your stride can help you become more efficient for longer heavy hikes.
