I have worn ASICS for years, and recently (sadly) had to buy a new pair of shoes (I always hate parting with a great pair!) - I bought these after being fitted at my local running store, and let me tell you - They are THE best! I need a little bit of a wider shoe, and these are the perfect size. Also, they really keep your foot in place when you're running - you have to WORK to run wrong! I have a long history of knee problems and have never once had pain when running with these!
