Wow! I'm so glad I posted about this; you have all given me a ton to think about.
Daniel - "How is the fit on the Tom's? Are they more or less true to size? I have wide feet and need a large toe box. How do you think these would fit?"
I would say that the Tom's that I've tried on tend to be a little bit narrow. I have slightly wide feet and the Tom's are right at the limit of what I can handle in terms of width. The canvas stretches somewhat (and I bought a laced pair that allows a little more flexibility as far as roominess goes), so they fit me like a glove. But any narrower and I probably couldn't wear them. You should give them a try, though. If you can find a retailer in your area you might find a model that fits. They are great shoes. (I love the pic!)
Eugene, Dan - I'm taking a good look at the MT100s, looks like I can get a pair at a decent price, which is great! These shoes look very appealing to me.
Robert - thanks for the wushu mention, those look fantastically comfortable and I'd never heard of them. For the price, I might have to try a pair! The dshack post is excellent, thanks for sharing it. I'm looking at Huaraches again after reading through some of the footwear listed there.
Mark - Traction is also one of my big concerns, so your feedback is helpful. Innov-8 seem like a little more than I want in terms of shoe, but I need to try a pair on... there's a retailer in my town, so I'm gonna check them out asap.
(edit)This is what I love about BPL - there are a ton of members willing to share feedback on some oddball stuff like this. At work on my breaks I'll update my gear list, weigh stuff (I work in a medical laboratory), and peruse the forum. My co-workers think I'm crazy when the see the stuff I'm talking about or looking at... vibram shoes, barefoot ted, cuben fiber tarps...
