So this weekend I tossed on my Five Fingers to go run errands in, as I had no clean socks for my Altras. Now both my Altra and my VFF running shoes are zero drop, so other than the lack of padding, I didn’t expect any real difference.
I can definitely say I walk differently in my VFFs. The next day, my calf muscle was SORE! I expected to feel some Plantar Fascia pain/soreness (and didn’t), but the calf pain? THAT was a surprise!
I run, because I am a runner. Having realized that I have always "been a runner" - even when I went years with out running, I am learning how it has integrated itself in all aspects of my life. When I started running in highschool, my perspective on life changed. Funny that I didn't realize how much it had affected it until just recently.

When I saw the title of this post my first thought was OUCH… Hope it feels better soon!
