I don't know specifically about the fit of the TM-Twos, but I posted a thread last week and several people on there have been discussing the overall fit for a variety of other ThirtyTwo boots. Usually a brand's footwear fits the same or very similarly with everything on its product line, so it could give you an idea of how ThirtyTwo boots fit.
From what's been posted so far, in most cases ThirtyTwo has been true to size as far as length goes while being wide but not too wide. I'll find out for myself on Thursday, when my Prions in size 13 (my exact size) arrive.
I've never tried on ThirtyTwo boots before, so for good measure I also bought another pair in 14 just in case they're too small, like how stupid Nike fits like a size 12 for their 13s (at least in their running shoes).
ThirtyTwo has free return shipping if you order directly from their site so you can try their boots on (so does zappos.com), which is why I also bought the 14s. I'll send back whichever pair doesn't fit the best. Be warned though, if you don't like waiting a long time they use FedEx (takes a forever). I think Zappos uses UPS but I could be mistaken.
Here's a link to my thread, which is also in the Boots section:
I'll update on ThirtyTwo's fit when I get home from work on Thursday evening. Hope that at least points you in the right direction for now, until someone else comes on here and tells you specifically about the TM-Two's fit.
