Once again I now understand why this shoe is a must for avid runners. The overall weight (compared to 993's), cushion (compared o Nike's), and the style offers the complete package for the recreational runner. My normal run time of 6-7 minute miles are easily accomplished wearing the Nimbus 9. The product that I purchased between the 8 and 9 were the Asic 2130, not even close. Once again the saying "you pay for what you get" rings true!
