Total thread bump, for anyone who's looking for some shoe feedback:

I ended up buying a pair of flat shoes in preparation for an upcoming trip to Ray's Indoor MTB Park. Ok, actually, I bought three pairs and sent two back. I learned that my size in Five Tens and Vans is 1.5 sizes smaller than my running/cycling shoes. So, for my size 8.5 foot, I ended up wearing a men's size 7. I also learned that, of the two pairs of Five-Tens I ordered, the Danny Macaskills are slightly lower in volume than the Freerider VXis. As a result, I ended up keeping the DMs. The uppers on the DMs are quite stiff, but are breaking in well after just a couple of wearings around the office (much to the amusement of my coworkers ).
