These shoes have been SOOO comfortable from day 1. I just got back from a trip to NY City and we Walked & walked & walked & me & my Keens held up better than our teenage kids & their sneakers. Never a blister or sore spot of any kind & plenty of room in the toes. I've had some nice hiking boots over the years but these have to qualify as one of the most comfortable walking shoes I've ever owned! I typically wear about an 8.5 but these 9's fit perfectly. Also because they're all black, they can be used for more formal occasions when on a trip away from home. They have been my only pair of shoes on 3 trips now & worked great.
