The quality seems OK, and the MC656 are indeed made in the USA with imported products.  I wear them everyday for work where I spend most of my time on the move, and they have remained comfortable.  If they don't feel nice at first make sure you give them break in time.. mine went from pain to perfection.  This specific pair is not even close in size though.  They were supposed to be 10 but fit like 11, and were 2E that fit like 4E.  The replacement pair fit better but weren't perfect, so consider ordering a half size smaller at least?

Being that they are tennis shoes, there is a ton of surface area that grips pretty well and they are very light weight.  The material seems to be good quality, as I haven't scuffed or torn them (I'm brutal on my shoes at work).  I like them specifically because they have the reinforced rubber at the front of the toe.  For the price I paid, they cannot be beat.  Are they worth MSRP?  Absolutely not.. in my opinion.  I'd say they are a decent mid range every day shoe but certainly not what New Balance used to be..

My 3 star review is for the lack of support, sizing inconsistencies, and lack of stability compared to the previous model.

EDIT:  After 3 months of every day use, these are beginning to fall apart.  I understand that they are designed for tennis, not every day use.. but I still expected them to hold up better.  The liners are wore out leaving virtually no padding.  The material has stretched a bit, making it difficult to maintain a consistent fit as well.  Lowered to a 2/5 star product, but still may perform better if used strictly for tennis.
