These are a replacement for another pair of Asics that I wore out. These shoes are great, even though the insole comes out unlike other versions. I was able to wear these on a long walk without pain or discomfort. The break in period was very short & they are comfortable as the others I have. One word of caution is that I would not run in these. They do not feel like my running versions, but are great for walking. I love the Asics line, and will continue buying their shoes. This is another great pair.
