I bought my asics 2140 from EastBay  The first pair I got were different sizes.  Both shoes said they were size 13.5, but one shoe was a good 1/2 inch longer than the other.  So I returned them, and they sent me a different pair.  This pair, the right shoe feels great, but the left shoe tilts my foot to the outside, which results in a sore left knee from just walking around.  Running is downright painful.  My feet may not be identical, but I've been running for many years, and never had a problem with any running shoes before, so I'm fairly certain this pair is also defective.  I don't believe that two defective pairs in a row is a coincidence.  I don't know if Eastbay is selling 2nds, or Asics started making crappy shoes (all my previous Asics have been great...), but I highly recommend trying these on in a store before you spend any money on them.

UPDATE: Before entirely giving up on the 2nd pair, I tried on a pair of the same shoes at a running store.  They felt great - exactly what I expect from Asics.  The problem was the defective shoes that EastBay was selling.  Not the shoe model itself.
