I purchased this NBM Mx608v4 7 months ago. I am a courier driver and put these shoes to work 5 days a week. I really like New Balance, however, I noticed the quality of material has changed.  In the past, they usually last at least 2 years. The shoes I just ordered, the soles still have alot of tread. There was a separation at the big toe area, so I had to shoe-goo it, hoping it will not separate again. I am very disappointed to say the least.
Looks like Leather but Pleather! On the positive note they lasted 7 months.....
