And now. . . for something completely different! Yesterday it snowed. Again. It's going to be one of those winters, apparently. It's not even Christmas, and I'm already wearing of removing snow. A couple of years ago, I got these vintage boots. Cobbies is the brand name. I got them because they are shearling lined, and I wanted some "heels" to wear when it was really cold. These boots feature 2 3/8" heels, which is right at about 6 cm. In other words, FLAT. Which suits me fine for the work I'm doing. I do consider them low heels in the grand scheme of thing, but they're flats. Let's be realistic.
Where things get interesting is the coefficient of friction factor. The forefeet of these boots are quite grippy, while the heels, once covered in ice, are dangerously slippery. This leads to some interesting footwork, worthy of a ballerina or Latin dancer. Walking heel to toe on smooth concrete after walking in the snow can lead to catastrophe, so it's best to do the opposite--toe first. I demonstrated this to my 16 year old. He said do what you got to do. A reheeling with Vibram would probably solve this issue.
