Background: 6'2", 235lb male @ around a 20min 5K & training 12-15 mi/week mixed among sprints & 3-6 mi runs.  My right foot has no arch and left only a mild arch.

I started on the MR1011 2 yrs ago as the only shoe wide enough and squared off at the toe-box to fit.  I was wearing a size 14 in some asics until a running store sized me down to a 13 2E in the 1011.  The 1011 wasn't the best shoe (a little stiff until dozens of miles were put on them), but the only thing I tried providing the control I needed as well as strong enough material to withstand hundreds of miles on training.

The 1012 is a much better shoe than the 1011.  My first ordered pair was a 12.5 2E, but was still too small in the toe and very stiff.  I moved up to a 4E and the shoe became perfect.  The shoe is very supportive, great at reducing over-pronation, has good toe-off transition (for being what it is, Franjenstein's monster's shoe) and the tight heel cup is nice.  I am not looking to run marathons, but I'd use this shoe for a 10k or 1/2.  For my 5K races I am still looking for a lighter, faster race shoe (but haven't found one with the same wide-toed last).

The only complaint I had was how stiff the first pair was (caused tibialis cramping), so I hope it's not manufacturing troubles, becauseI bought a second pair.

Oh, and the "N-lock" laces that come with the shoe are very good at reducing the amount of lace slip and shoe loosening.
