I thought it would be fun to try some too, but opted for these Merrells that look like normal shoes. The sole is so thin I can feel rocks underneath my feet (which I like. It makes me feel more connected to the ground I'm running on) but is thick enough that the rocks don't hurt. One of the reasons I bought them was to train myself to land on the front of my feet instead of the heel, and because the heel on these is so thin it feels pretty natural. Eric and I have also been learning about the benefits of running barefoot, so I thought I should give it a try. The first time I tried my shoes I was incredibly sore in my calves the next day, but as I've continued to run in them the soreness has decreased significantly. I'm guessing after another week I'll be past the breaking-in point. I've always felt a little guilty for running so much because it's so bad for the joints; running in these helps me to feel better.
I just love the fact that our feet were made by God to run without any help from shoes. It's pretty cool.
