I put indoor/outdoor carpet tiles in my basement. 2'x2' each. You can glue them if you want, but I used double faced carpet tape. Some have self stick backing, but I didn't go that way. They can be easily taken up if there is any water leakage (haven't had that issue). If they were to get wet, pull it up and let it dry. Get an extra box and if something gets stained or cut, just replace that tile. It did help to cut the higher frequency sound bouncing, is easy to install and comfortable to walk on.
