I bought these shoes not really knowing what to expect. I saw all the good reviews so I decided to give them a shot. And I am sure glad that I did! This is the most comfortable pair of tennis shoes I have ever owned, and I have owned MANY pairs, and all brands. I didn't have to break them in before wearing them either. I wore them for a 13.5 hr shift at the hospital last night and they were wonderful. My feet didn't  hurt like they normally do after a few hours. I have a flat arch so I believe these help give me the right support I need. I am going to buy another pair for sure.
