Due to my overpronation, I have bought the same style Asics running shoes for years, actually 2 decades.  I've always loved them for their quality and reliability.  However, in the past two years, the quality has definitely decreased and the sizes are not accurate.  I've tried several different pairs over the last two years and a standard medium width is now too narrow.  I will need to start buying these shoes in wide, which is very disappointing because there not as many colors from which to choose.
I've read other reviews and my opinion seems to concur with others.
Asics--I am asking you to improve your quality control and bring back the shoes that everyone loves!!!
