Based on what I'm reading about the 928 vs the 927, this may be relevant:  I purchased a pair of 927's to replace my current 927's and was surprised to discover that they did not fit the same (new ones were narrower); contacted seller AND new balance--both denied that there was a difference; I traced the sole, measured the circumference--there IS a difference--also discovered the new ones were made in Vietnam instead of China.  Got no satisfaction from either; fortunately Amazon came through and got me a return shipping label to pay for returning the "defective" product. I'm looking for a new brand of shoes--so far unsuccessfully!  Thank you  AMAZON!
