I'm 50 years old and have been wearing Nike sneakers since I was a child on a cross country track team. Although I am not such an avid runner these days, I will say that these shoes provide great stabilization for people with flat feet that tend to over pronate.  I have tried many other brands; Asics are a good second place, but New Balance, Saucony, Merrell, Adidas, etc, don't work for me.  This particular model of Nike, the Lunarglide, is awesome, lots of cushion & an easy ride.  They also feel very light on the feet, very comfortable.  I had 2 pairs of the Lunarglide 6 that lasted a good while.  I just upgraded to 2 pairs of the Lunarglide 8, this black & white pair & the light blue (Ocean) with white.  I wear these for everyday activities & at the gym.  For my money this Nike model is the best sneaker for people with flat feet.  I am a big fan & highly recommend.
