I did some research and initially I was going to go with the Vibram Flow because they seemed designed for water sports with the Neoprene upper but then I figured it might be too hot and sweaty if I wanted to run in them. I went with the KSO's. I also got the Injinji toe socks.
I heard you should ease into running in them so I decided I would start out with 1 or 2 miles. (I later read that they recommend between a quarter mile and a mile.) As I crossed the street to start my run, the Vibrams felt good. I felt like I was barefoot but without all the rocks poking my feet.
Trying to figure out the best way to run with Vibrams, I started just running on the balls of my feet without my heals touching at all. I couldn't run slow like that. It was like a dead sprint for the first quarter mile. That was not going to work. I stopped to walk and catch my breath. I started running again, slower this time, and started to get the hang of it. Instead of running on the balls of my feet or with a heal strike like I do in running shoes, I landed more flat footed. Like a mid foot strike.
The KSO's were surprisingly comfortable on my feet but I could really feel the surface I was running on. Running on the grass was soft and cushy. Running on the pavement was hard. I was feeling good so I went for the whole 2 miles.
They won't replace my running shoes but it will be fun to mix those in the rotation every once and a while.
The next day I expected my calves to be really sore. They were a little sore, but not bad at all.
