Being able to design your own footprints is a very important skill for any PCB designer, regardless of what software you're using. Sooner or later you'll always run into a component for which you won't have a footprint readily available, and making footprints in Altium rarely takes more than a 10 minutes.
Assuming your socket is through hole with a 100 thau pitch, you'll only need to place an array of pads. If you set the grid to 100 thau then they will even snap in place automatically. In the time it took you to write that post, your footprint would be ready.
Good luck!
