I think I've never been this nervous in my whole life about a trip. If you could see my second bedroom/office right now you would know the reason of part of this nervousness. If you could see my to-do list at work you would get another part of this reason. I've abandoned my perfectionism some years ago, but it seems like it never actually went away.
But I was not going to talk about my trip here... I'll discuss about... The new Nike Free technology! I'm not a friend of walking barefoot, but it really seems like all shoe companies right now are aiming towards making you feel like you are walking wearing only socks or something. It is strange, but not at all unexpected. The shoe evolution started with just pieces of cloth (a sock), then moved to a sturdy platform tied to your feet (sandals), then technology evolved on the sturdy platform side, increasing and decreasing its flexibility and the tying part, also increasing an decreasing flexibility and how much it protected the top part of your feet and calves. Shoes in this whole evolution were synonymous to "protection."
Then we entered an era of "shoes are supposed to offer you more than just protection" and then we got to the Nike Air type things, where shoes offered support, and spring efect to decrease impact on the floor and use this impact energy that is mostly wasted on our bone structure to give you force back to move faster ahead. Thousands of variations were proposed, looking more or less like springs on your foot.
But the world wasn't happy. The era of flip-flops was not disappearing, it was gaining strength. With the improvement in materials, it started to be possible to get back to the sock principle and just add a little bit more grip to it. And that's where we are right now. A sock that is more padded. Allows you to walk on glass, but still feel like you are actually touching the ground.
I'm an engineer, so I can say that I miss the "Nike Air" wave. It just makes more sense in an energy use standpoint. Not that it's gone, but it just became harder to find those shoes as they are currently deemed unfashionable.
Anyway, good that I was able to just talk about useless things for a while. I need to free my mind from other things.
