Goji, I wouldn't send them back just because they look wierd - the're just foot shaped
and they make more sense when you run in them (honest!).
However 110s do come up small so if you think they are too short, they probably are! - my first pair were a bit marginal (never caused a problem, but I felt they had the makings of black toenails) so when they came up for replacement, I sized up. I'm now on my 3rd pair!
Before the 110s, I had 3 pairs of 101s which were also great but more restricted in the toe-box and I soetimes got a rub on the side of my little toe from the stitching of the overlays (Note: I always run sockless) which appeared to be a fairly common complaint.
Neither of these shoes is a true UK-muddy-conditions shoe, though the 101 is better than the 110 by some margin - I wish someone did the 110 with a Mudclaw sole (and at New Balance prices!).
