Here's my advice: Zappos sells some of the Five Ten line. Maybe they carry the Tevas as well. Order a handful of styles and sizes. Return what doesn't fit. Shipping is free both ways, so you don't have much to lose. I ended up with the Impacts in a size larger than what I normally wear if memory serves (I can check at home tonight), but I had to go through a few models and sizes before I settled on them. I like them for mtbing and I assume I could get used to them if I had to for road riding.
