You can read more about these shoes here, but here's my opinion about these running shoes.
As I have said on this blog before, I have not yet found the "perfect" running shoe. Each one has its own quirks, which tend to injure me at some point or another. In fact, the last pair I got were so bad that I had to return them in a month. Fortunately, the place I get them from has a 60-day return period, regardless of wear.
I was matched with these New Balance shoes and was excited to try out a new brand. At first, when I started running in these, I felt soreness in my foot arch the way it did in the previous pair. However, I soon realized that this was more of me not recovering than the shoe itself.
So I've given this shoe another few months, including a marathon, and am finding that these will work for me. They aren't as cushiony as I'd hope, but perhaps cushioning isn't that critical to me, as I've been running pretty well lately. Most importantly, they are NOT heavy, which is characteristic of shoes that I need (motion control/stability).
Would I get New Balance again? Maybe, though there are some other contenders I'd like to try out first. I'm a couple of months from getting the next pair.
NOTE: I have stopped counting the mileage on my shoes, if for no other reason than laziness. I have a rough idea of time vs. miles run, so I just know I need to change my shoes periodically (approximately 2x/year -- I run about 1000 mi/year at best... see bottom of blog for those stats).
