If you run wearing shoes then you'd better make sure that they are good ones.
The problem is that most of what passes for "good running shoes" are in fact crap.
When I was a kid I ran barefoot most of the time. In school my running shoes were converse or Keds. Thank God I was out of high school before modern running shoes came on the scene.
Because I run around barefoot as much as I can, and have for most of my life, I have what we call here in the States "wide feet" (what would be called normal, healthy feet everywhere else).
When I was living in Africa one of the things that stood out was how healthy people's feet were.
(Yes, I look at people's feet, and watch them walk, run and stand. It's something I learned from my grandfather as a kid and have kept up my whole life. You can learn a lot about a person by watching them walk).
One reason for this is that the most common footwear are flip-flops and sandals made from old tires (the only thing the Maasai will wear)
Here is a picture of a fellow delivering sugar cane. He will pull this cart, running not walking, from sunup to sundown and never suffer from shin splints even though he wears nothing but flip-flops. I know this because I talked with these guys every day and asked them about such things.
Running in "civilization" I often want more protection for my feet than sandals offer, but I don't want to use the over engineered monstrosities that pass for running shoes.
My solution has been to use "Wu Shu" shoes. These come from China and are designed for martial arts.
They have no arch support, a thin flexible sole, no build up in the heel, and almost no padding. Practicing martial arts you really need to feel the ground and to be able to get onto the balls of your feet, which also make these a great shoe for running. The shoe is quite light, has a sole that allows the foot to roll to the sides and offers very good protection from the sort of detritus found on the streets around here. They also have a very wide toe box. This is one of the very few shoes that I can feel comfortable in toe-wise.
Perhaps the best thing though is that these shoes are very inexpensive, about $20 US retail and half that if you get them wholesale. The place I get them from, Kwon martial arts supply allows instructors to set up school accounts for substantial discounts.
There is one caveat though, the shoe tends to size a little small. I get mine a half size larger than my street shoe size. Considering that I can get about ten pair of these shoes for the price of one pair of "premium" running shoes it is a small problem.
