> Something like 50% of runners get injured in a given year.

That's because most people use bad technique and would probably benefit from strength training as well. Sitting all day and then expecting your body to run for 30-60 minutes and then sitting again will lead to high risk of injury. I see a lot of people run like they're walking with longer strides, or hunched over, or any number of bad habits. The feet should land under your center of mass, not in front of it, and the turnover should be pretty fast. Short and fast steps instead of long and slow. Don't run too fast, use your core for stability, and keep an upright posture, slightly leaned forward at the ankles.

Look up proper running form, do some drills, and add body weight strength training a couple of times each week if you're thinking of starting running.

that is because most runners use padded shoes, which enable you to run in a totally unnatural way.

>this kind of collision leads to a rapid, high impact transient about 1.5 to as much as 3 times your body weight (depending on your speed) within 50 milliseconds of striking the ground (see graph a below).

>This is equivalent to someone hitting you on the heel with a hammer using 1.5 to as much as 3 times your body weight. These impacts add up, since you strike the ground almost 1000 times per mile!

It is impossible to run this way with undamped shoes or barefoot.

I recommend this book (not affiliated):


is really fun to read, it is about a indigenous tribe in mexico which run in sandals cut from old tires, for 24 or 48 hours straight. In there is a reference to another study where they found a correlation between cost of the shoe and the rate of injuries: more expensive shoes with better damping had higher rates of injuries, they weren't expecting this.

Our legs evolved to store the energy in our tendons and release it to propel us forward. A QUARTER of the bones in our body is in our feet! Humans evolved to be the best endurance runners on the planet, being "naked" (without fur) is actually an advantage for running, enabling us to cool down our bodies by sweating. There are still tribes hunting their prey by running after it for prolonged periods till it collapses from overheating. There are races for horses, humans started to compete in. Initially the runners where ridiculed but someday a human won the race.

And most importantly, don’t bereft your brain from useful feedback from your foot! Use thin (unpadded) rubber soles on your shoes. If your feet are getting painful, probably they are saying something useful about your knees as well.
