Check out the New Balance Winter 110 runner!
What makes them special is their combination of low weight and rock protection, but what makes them popular is their fit. They're a bit like the race/comps of trail running: they fit universally snug but not tight enough to make your toenails black. An extra-grippy sole doesn't hurt either. They have a zipup "outer sock" is water resistant, keeping the water out of the inner laceup shoe, and keeping you running through our miserable Canadian winters.
