Every single pair here is made by Asics. Their quality has gone from great to mediocre in the 12 years I have been wearing them. I can document each progressive change that actually made the same shoe (like the Gel Kayano) worse. I think they did this intentionally too.

I can never seem to get rid of my running shoes after their intended purpose ends, usually around month six. But they still work fine for walking and other sports. And so my stack of shoes is alive and well by my door. I actually just dropped off four pairs at Goodwill too. (Click on the photo to see a larger picture on a separate picture page.)
