I was out on a run on Friday when I started getting some tightness in my shins. It was strange because I haven't had any problems with that the entire pregnancy. And then I realized - maybe it's my shoes? Because I haven't done a weekday run in my Vibrams in at least a month. And they certainly felt tighter.
In general, any running complaints I have I usually blame on my shoes. It's a fairly good guess. The majority of running injuries come from wearing the wrong shoes. Shoes are a runner's primary investment, the most expensive part of the hobby.
When I started running more than just a couple miles here or there, I got fitted for shoes at one of the big name running shops. "Fitted" means they had me run on a treadmill and evaluated my gait. I tend to under-pronate, but only slightly, so a "neutral" shoe works best for me. They put me in a pair of New Balances and sent me on my way.
It was the first time I'd ever been in pain running. My knee started hurting before I hit the first mile. Those shoes went right back to the shop and I requested a neutral Nike, since I'd been running in those since the dawn of time. My one bad experience has made it difficult for me to switch brands! I know most runners love Mizunos, Brookes, and Hokas, but I stick with what I know.
So lately I've been wearing my Nikes on all my weekend runs and I think I'm going to have to start packing them in my workday run bag. I'm hopeful that once my feet return to their pre-pregnacy state I'll be able to switch back to the Vibrams during the week - they're so much easier to pack!
