Heel Landing

This was touched upon in another thread but I'd like more understanding on when/why to choose different types of foot placement during a glidewalk. Everything about this style of walking has been soaking right in to my movement patterns with a sweet AHA feeling except for the heel strike. It just doesn't feel right. Especially when contrasted with the feel of fox walking, learned from the modern primitive-skills community. When not actually stalking (higher knee lift, hinged body for non-human outline) the ideal fox walk is the same as glidewalking until the end, when you place the 5th metatarsal down first, rolling in to the big toe and down to the heel, just like with intuitive barefoot running. That Harvard video mentioned in the other thread is great, here it is again http://www.barefootrunning.fas.harvard.edu/ In the other thread Esther mentioned the heel strike being natural on soft, predictable surfaces and a midfoot strike being natural on hard surfaces. Seems logical, the landing gets more forefoot-y as the potential for impact increases. I'll give it a try tomorrow. I'd like to know if/how the pattern changes with a fore/mid-foot landing. Thanks very much. Ben
