Keeping Your Feet Off the Ground!

Ideally, if we could run without ever touching the ground, we would eliminate all running injuries – except for the odd, being run over by cars, falling off clifs, etc..
Seriously, puncture, abrasion, impact, etc., virtually all running related injuries are the result of the forces, the friction, and impact of our feet (or shoes) interacting with the ground.
Most of us do attempt to keep our feet off the ground, by wearing shoes. But, that simply moves the ground forces, to the bottom of our shoes, which are attached to our feet, which are attached to – well, you get the idea… And we continue to pound, skid, twist, push, etc., barely aware, that we are pounding, skidding, pushing, etc..
The next best thing to keeping our feet off the ground, something a bit more attainable, would be to barely touch the ground, to reduce, if not eliminate friction – skidding, excess pushing, twisting, slipping of the feet. If we could distribute the forces across our entire sole, our foot landing on the road at precisely the same speed and direction as the road is traveling underneath us, perhaps even decelerating our foot, as it touches the ground, just like a space shuttle docking with the space station.
The difficulty, of course, is that we are rarely aware of these problems. Most of us run in a kind of dazed condition, not really paying attention to these ground forces.
Some of the wealthy, or elite runners could have coaches watch, and let the runner know when their running technique is getting sloppy. For most of us, this sort of personal coaching is far too costly. And even if we could afford it, for many of us, it takes quite a bit of repetition before we learn something new, and make it habit – as soon as the coach is gone, we go back to our old, sloppy ways of running.
If only we could have a coach, who worked very cheap, maybe for food, and could be with us constantly, someone to remind us, emphatically, perhaps by hitting us on the palms of our hands, or the soles of our feet, with a ruler or something, with each and every step, when the ground forces change, so we could make adjustments, and keep on running gently.
Maybe, something like those shoes with computer chips that change the tension in the springs depending on how hard we are pounding our feet into the ground? If only we had something like that, but even more sophisticated (hey, as long as we’re dreaming, let’s go fully sci-fi!), built into our body – a complex system of sensors, maybe concentrated on the soles of our shoes, in direct contact with the ground, sensing every little detail, of each and every step, and some sort of very complex computer (the most powerful ever built) attached to those sensing devices, to process the information, and maybe a way for that computer to communicate directly to our muscles, so we could make the necessary adjustments to the way we run.
Then we could step more gently, like we’re sneaking up on someone. We might actually start running more efficiently, more gracefully, more “naturally” (oh the irony!), like, maybe, in some ways, better than, any other running creature on this planet.
We could even shift our weight, instantly, when we stepped on sharp pointy objects – if we could figure out a way to implant these sensors in our skin, we might even be able to run, dare I say it – - – BAREFOOT!
And with this kind of instant, and continuous interaction, we might just find running more stimulating, exciting, maybe even, FUN!
But, of course, that’s all science fiction. We’ll have to wait until scientists perfect artificial intelligence before we could have anything like that.
If only we had a brain!

limpkimp,
The problem with those long, extended strides, is they keep ending with a BANG! And that BANG! is wasted braking energy – not completely wasted – most of it goes to destroying knees and spinal columns – which I suppose is fine, as long as that’s the goal.
Running fast with shorter strides is actually easier. Because you’re spending less energy slowing yourself down.
1. make sure your torso is vertical.
2.Lift your feet quickly, frequently (think roadrunner cartoons – beep, beep).
3. Bend your knees, as much as you can, while running (actually, this is the same as lifting your feet).
4. Don’t push yourself UP into the air, try to keep your hips low, so your knees stay bent.
The bent knees are KEY to fast running. When you find your sweet spot, your natural springs, you can relax while running, and, as long as you keep your cadence fast, your torso vertical, and let your hips lead, these natural springs will return practically all of your energy FORWARD.
If you stretch your stride out in front, the jolt you feel, is the earth pushing you backwards, that’s why your friends have to compensate for that braking by pushing off harder.
So, it may take a bit of time to master this much more efficient, gentler running technique, but, theoretically, it will lead to running with less effort and stress, which means you can run faster, and/or longer with the same energy expenditure. In my case, it certainly was the case, though I waited about 10 years to prove it in races.
Oh by the way, once your body is moving faster over the ground, your stride length will increase – in distance – even though it is short in time … the faster you’re moving forward, the further you travel forward with each step … however, quite often, by trying to reach out for a longer stride, you slow your stride rate down, hit the brakes with each landing, slowing your forward motion, and your stride length (distance) can actually become shorter than it feels – spending more time in the air for each step, does not necessarily mean you’re traveling forward faster.

Barefoot Ken,
I just switched to running barefoot and its awesome. Love the feel, and it makes running fun. That being said I love speed, and I just don’t see how you can compete with individuals who take long, extended strides. Timing myself i’ve found this to be the truth. How can I speed up running barefoot? Increased cadence helps, but even then I feel that without lengthening my stride, it is impossible to be competitive. So in essence, is it possible to post really good times barefoot, or should I practice barefoot and switch into running shoes come marathon time?
Thanks,
LK
