As I get older, my feet seem to be more picky. Some shoes, when you wear them all day, there is something about them that might be uncomfortable. These shoes, when you put them on and wear them for 9 hours on a concrete floor, constantly moving, just let me say that these shoes make me forget all about my feet until I get home from work and take them off for the night. I very rarely write a review on a product but I just had to give my opinion...BEST SHOES EVER!!!
