I'm lucky to be in the position I'm in. I've recently been educated by a customer who found us on www.facebook.com/sockwa and is loving his Amphibians. We've been writing about different details regarding sole design and recently, the Pose Method of Running.http://www.posetech.com/pose_method/pose-method.html
As a mechanical engineer, I'm enamored with the bio-mechanics of humans running, and I've just begun learning about this method of motion. It's fascinating to dissect human motion and to try and understand each sector.
Keep the lessons coming.
