I would imagine that anyone in the IR&DA section has read a fair bit about the structure of sasquatch foot, and is well used to the drawing of human v sasquatch foot.
The theory of course, is that a sasquatch print 'creates' an arch or ridge of sorts in the print by the pressure when it moves onto its toes and steps forward.
Up until now, I accepted that without question, but this morning, my car wouldn't start, so I walked the couple of miles across farmland to my office - I had my huge walking boots on - as you know, I have a size 15.5 US foot, so these boots measure about 15" from toe to heel.
because it was slipery, and because of my size, i tend to walk 'sasquatch' like across slippery ground - ie, i don't lock my knees - partly because its slippery, and partly because I have an old rugby injury, which hurts my knee when it locks sometimes.
what I noticed was that whilst walking like this, you don't actually tend to step forward onto your toes as much - more, you lift the entire foot, and move it forward.
Any ideas ?
