Hi all sorry to join late, I have had some Nike Span Triax (too soft), Mizuno Riders & Creations, 2070's and NB1040's all have given me slightly differing problems, most likely due to having one leg a bit longer than the other. I am now on my second pair of Pegasus 2002, their wide straight last seems to give stability while the rear "crash pad" seems to gently halt my mild over pronation. I cannot tell you how much of a joy and benefit to my race times to be able to run more than a couple of months before being "injured". My advice is to keep looking, and ease into each new shoe slowly, if possible. Good hunting.
