<My friends there have made the offer to be guarded by their own AK 47-toting body guards, but I don't know them so I have refused. > Being able to put a long way between the attackers and yourself would be good, so good running is selected. The slow runners who got puffed would be caught and eliminated from the gene pool. Catching deer might also be handy.

Regarding bare foot running, having grown up in bare feet and running a lot, I can attest that bare feet are far more comfortable and fast for running, requiring less energy to do it.

To understand the physics of the energy saving, tie a couple of bricks to each foot and run with those, then try it without bricks on. Or some other heavy weights if you don't have bricks or they are tough to tie on. While a shoe is not as heavy as a brick, it does have mass. So accelerating them to foot speed and back to stopped every step takes a lot of energy over a long run.

A bare foot is also streamlined, so there's less air drag compared with shoes. The feet travel at much more than the speed of the run, going from stopped, to over twice as fast as the speed of the runner's body then back to stopped again in an instant. youtube.com Since air resistance is the square of the speed, and the foot is a big flat surface against the air at its maximum speed, air resistance is a big deal over a long run.

There is also cooling. I get really hot during 10 and 20 km runs and cooling is a big issue. More so than getting air into lungs and blood around the body. On hot days, heat is the limiting factor. When running in -5 degrees, heat isn't a problem and bare feet are not practicable on snow. Shoes are nicer then. But on hot days, wearing shoes insulates feet against cooling. There's a lot of cooling from feet due to radiant heat, conductive heat loss, and latent heat of evaporation of sweat. Wearing shoes stops that cooling.

There's also elasticity. Bones flex and act like springs. So do ligaments. Taking the feet out of action with shoes means a significant amount of elasticity is removed. The long leg bones are quite springy but when every bit helps, those nice long foot bones are handy too. If running shoes were made like springs, then running shoes would be great. Big long running shoes like these ones might be good but the design looks clunky and bad.



It's also pleasant to run barefoot, as you can feel things. Running in shoes is like having a shower while clothed or washing your feet with your socks on.

Feet get a nice leathery sole so running over sharp little stones is no problem. 20 kilometres in bare feet is fine. Hard surfaces are best as there's no energy absorption by squashing the ground. Running in sand is very hard work. Dry grass on hard soil is fine but best is the 'ard 'igh road.

Feet also get very strong. I've never had foot problems. With longer distances I would sometimes get side of knee ligament problems.

The big curse and reason to wear shoes is broken glass! Decades ago it was much more of a problem because milk came in bottles which milkmen dropped. Drinks were in bottles which people threw. Now milk comes in plastic bottles and beer in cans, with soft drinks in plastic bottles and cans. The environmental improvement with plastic bottles for liquids has been fantastic.

Kiwi culture still includes a large bare foot component. You will see adults in bare feet frequently, though not so much around downtown. vagabondquest.com
