its all in the form. there is a term used in running parlance: "biomechanically efficient runner"
it basically means someone who lands midfoot/forefoot with knee bent, and foot landing near under the body (not ahead). these runners benifit from great form to the point that shoes are well only there to protect the feet from the elements. so the less shoe the better (hence the use of super light running flats for guys even running in marathons).
and tycoon, dude if you're training in boxing well then the whole boxing stance defense/offense is basically always on the balls of your feet. so just the way you bounce around the ring (like ali) makes boxers more biomechanically efficient in every way (think of all the jump rope and punching, its all bouncing on the balls of the feet and being super light on the feet).
so that means banging out 5 miles with great lightfooted/forefoot/midfoot/ landing is easier on your knees because of the ideal form.
even traditional boxing shoes (super thin leather sole/snug fit/flexible) promote it.
