I am on my feet a lot at work, I have worn this shoe daily for at least 10 years. I have worn out my 5th pair, I had 2 brown pairs and 3 black pairs. The sole never split on the brown shoes. But the sole on the black shoes all split right across the width of the foot within a year, but like I said I wear these daily, all day. If you purchase the brown pair and the black pair in the same size, the black pair will be a little smaller, you need to get a 1/2 size larger in the black pair. These shoes are leather and they do stretch. These are the most comfortable shoes I have ever worn and the most supportive. In other shoes I tend to have weak ankles and the bottoms of my feet will hurt. They look great with black dress slacks, the trouser type, and great with jeans. But they will not work for dressier pants, cropped pants, ankle length pants, skinny jeans. I would give them 5 stars except for the split in the sole on the black ones.
