Pretty normal. Sole wear is probably the last indicator one has of shoes that are done.

You can still use the ones you decommissioned, but twice or more a year is a pretty normal replacement interval for daily drivers when you are on your feet all day. Your body will thank you.

I use my decommissioned work shoes for things like painting, or yard work, or pouring cement when I know my shoes are going to be destroyed and that is okay.
