These are the most comfortable shoes I've ever put on my feet.  The recommendation is to wear them for short periods of time until you get used to them.  Well, I didn't need to do that.  The first day I wore them to the Mall, and walked in them all afternoon, and I didn't have a problem at all.  I love these shoes, and wear them at work where I walk on cement all day, and have been doing so now for more than 30 years.  I try to wear comfortable shoes to prevent foot problems.  I have finally found the answer to happy feet!  Thanks so much, I'm going to buy another pair for home.  Kayte
