The only sneaker that has worked for me was the 1123 (the model that the 1540 is replacing) until this came around.  I wear 3/4" custom orthotics in my shoes because of a leg length discrepancy, and this shoe accommodates them well.  The 1123 is ugly, but I was going to order it again until I found that my size is no longer available.  The 1540 seems to be very similar in design to the 1123 but it is available in black. Thank god that it is available in black, because in any other color these shoes would look 'special'.  The 1540 seems a tad shorter than the 1123 in the same size, but I still fit.  For anyone that is not familiar, this shoe is best for people who require a lot of support.  I don't know if I would wear it for running, but I don't run any more anyways.  I use them for the gym, working out, elliptical, etc.. The good thing about this pair in black is that I can wear them with jeans and they won't look funny.  I expect this pair to last for a very long time, because the 1123 outlasted any pair of sneakers that I ever wore.  It is upsetting that I will have to pay $20-$30 more for these but it is worth it to be able to get them in black.  Totally inconspicuous.
