Totally got these with my Christmas money and have put in two 2 mile treadmill runs.  A few things I’ve noticed already:

1. My calves and shins are sore in ways they haven’t been since I started running.  This means something, right?
2. I’m also feeling something in my knees – I’m not sore, but am definitely experiencing different kind of percussion.  I don’t know if that means I’m nailing a midfoot strike or that I’m just getting used to the shoes.
3. My feet are clearly different sizes, and this is much more noticeable when my shoes are more articulated.  It’s not bad enough to necessitate buying two different pairs of shoes, and I’m sure I’ll barely notice once I’m back outside
4. Hooray! I have new shoes! For the first time in almost three years!

Also exciting: Shane got me a Garmin GPS watch thingy!  I don’t have any exciting data to show you since I’ve only run inside since Christmas, but I’m pretty hyped about it.
