I have run off and on for 33 years, mostly in the range of a few miles a day.  My goal for a running shoe is comfort, plain and simple.  You will likely hear that you have to spend at least $100 for a good pair of running shoes these days and it is largely true.  Durability is not just a function of tread-wear for me.  A shoe has to maintain the integrity of the midsole and assure heel stabilization to keep your foot in a neutral position upon landing. Here is where this Gel Nimbus failed me.  I am a neutral runner and the shoe does some strange things as it wears.  The gel inserts are only on the outside of the shoe.  In my case, the rear inside sections of the outer sole collapsed into the mid-sole.  The gel on the outside kept that part of the sole stable.  Basically the shoe began to shift inside upon impact, significantly at about 100 miles.  Further, the front section of the sole had worn out at around 125 miles.

The Asics Gel Nimbus 14 is too soft, in my opinion.  It needed more gel reinforcement on the inside of the shoe.  The sole wears out too quickly.  It is simply, not worth the money.  The uppers wore very well, so I was left with a good looking shoe that was useless after half the mileage that it should have given me.

I would say that I just had a bad pair, but I had bought a second pair before I noticed the problem with the first pair.
