Lot of complaints about NB1540 can be traced to buyers assuming the 1540 has the same fit as the 1123. If you consult "Shoe Fitter" via a link from the NB1540 page, it indicates the 1540 runs 1/2 size smaller than the 1123. While this change may have been kinda dumb on NB's part, the fact remains that buyers should NEVER assume a new model will fit the same as the model it replaces.
