Thanks for this, and the video you posted. I've been wearing Skora zero-drop shoes for about two years now, and I've only recently gotten back into running for exactly what the guy in the Ted talk said - for the fun factor. It's because I love how it feels! Granted I run on trails in the woods that are soft and covered with pine straw. It wasn't really my intention to pick up running again, but as I got more and more into feeling my whole foot on the ground it kind of naturally evolved from walking to dancing to running. Using the zero drop shoes, I feel more in touch with the ground, like I am giving it a massage with my feet!
