Easily, for some types of shoes. In dry weather, I don't care. Small holes in the shoes don't really matter much. In wet, though, it is baffling how quickly I can go through shoes.

This was back when I walked about two to five miles a day. Just in the office, the same shoes can last much longer.

For that matter, most of the change has been in the wet season. I wouldn't be surprised to find the shoes flat out wear faster in that environment.
