Let me just say I'm a fan of Nike. I own 3 pairs of Flyknit Lunars . The first two pairs I ordered my usual size 5.5 and they fit like a glove. However after just a few months of wear they developed a hole where my big toe is. I use these for running and for everyday walking. I will also admit that I walk a lot. When I lived in Boston it was normal for me to walk about 5 miles a day. In NYC you walked everywhere so reaching my daily 10,000 steps wasn't very difficult if I wanted to. Adding running into the mix and there is a lot of wear and tear. However I would expect these to last longer than a few months. I'll admit that a hole in the sneaker is not really a big deal. No one would probably notice except myself. My husband suggested that maybe they were too small, and I should order the next size up. I'm hardly ever a size 6 in anything, but I said sure, why not? I ordered another pair in a size 6 and sure enough 3 months later, I got a small hole. So
