"I can say with confidence, the New Balance 610v2 were by far and away the best running shoe I've had, in terms of running comfort and weight.
However, while I could run 10k+ in them, I couldn't walk 2k without suffering from massive blisters in the rear of my heels.
Also, an obvious price had to be paid for the thinness of the material that made them so light, and that is their life span. I have small feet for my size, though they're wider, which means I burst the shoes at the little toe area.
I'd take more weight for an increase in longevity, as both the tread and the support were mostly okay, though the uppers had split."
