I can't find specs for this bike (as far as geometry), but I have a Marin Belvedere (aluminum frame flat-bar commuter) and I could never get my size 12 heels to clear using Performance Transport Pro panniers in back. I could have experimented with more adjustable bags (like the Ortliebs I currently have) but used that as an excuse to build a new LHT and buy Ortliebs. (By the way, I bought a used Bob Yak for $125, but only because someone I remotely know was selling it. I don't like riding with it as much as I like 4 panniers, and I'd hate to deal with getting it out west or to Europe, along with the bike.)

Anyway, my point in all this rambling is this: with a 14 shoe I would not assume that ANY bike will fit without strike. REI is a great store that carries this bike, lots of racks, and several lines of panniers, including Ortlieb -- get into a store, have a mechanic at least cobble a rack onto the bike with zip ties (if they don't want to mess up thread paint by really installing one), and hang some Ortliebs off of it. You should be able to tell immediately whether it's something you can work with.

Other than heelstrike, though, I love my Marin. Great bike value in my opinion. My daughter has taken mine off to school for awhile, but it is great to have around as a loaner bike for people who have bikes but not touring bikes.
