These are designed to be printed in TPU. (I use Sainsmart TPU 95A) You can use a non flexible filament, but I highly discourage it for comfort reasons.
You will need M5 Threaded Heat Inserts @ 8mm in length to secure in the back end of the footpad. Use your soldering iron to slowly melt and set them in the holes. This kit is pretty nice -https://a.co/d/1ZZ9WmV
