I purchased this shoe for my son who is a Marine.  He runs approximately 10 miles a day (his choice) to maintain his physical endurance.  His previous shoes had no tread left after just six months.  His only request:  make them New Balance!  He received them for Christmas and was delighted.  The extra cushioning is great for his knees and the tread is superior for running on trails which he does frequently where he is stationed.  A great bargain for the price.  I would definitely recommend them.
