I plan on using them for running 5k on a hard trail, I was thinking that the Sprint was the model for that, but I see these comments on the KSO, are they good for running?
BTW, the book I was reading that got me into this is "Born to Run". Turns out humans evolved to chase down wild animals by wearing them out. We may not be able to run as fast as a deer but we can run further. Oh and hey. Barefoot Ted features prominently in that book.
