So, I finally bit.
Yesterday was a stairmaster day (mostly so I could study and exercise, or, really, feel like I was studying).
I did some weights and realized what a wimp I've become.
At the end, I decided to knock a few miles off on the treadmill. So, after 20 or so minutes of running my foot started to hurt. Pretty standard on the treadmill for me. There had just been a discussion on the ultra list about barefoot running on the treadmill. I thought this sounded kooky, but as my foot ached I started to wonder: "what would it feel like"?
So, I slipped the shoes and socks off, got on the treadmill and started walking. Hmm, my foot started to feel good almost right away. Odd. I cautiously turned the speed up, just to a slow jog. It felt...well, it felt really wrong but not physically, just mentally. Like I was violating some running rule. But, my foot felt great, so I kept going. I ended up only doing about 1/2 a mile but it was fantastic.
My feet did hurt last night; it was weird to be sore in my feet.
I'm not sold, but I'm optimistic about adding some barefoot cross-training to strengthen my feet/ankles.
