This tutorial provides 2 ways to remove the footer widgets in any Genesis child theme.
Based on this question from a member of the StudioPress community forums :
Your solution works perfectly for eliminating the sub-footer on outreach pro. However the 4-column footer remains.
1. To remove the footer widgets, add the following line of code to the front-page.php file before the closing genesis(); tag
remove_action( 'genesis_before_footer', 'genesis_footer_widget_areas' );or
2. You can add the following code to your child themes functions file.
Change the is_front_page conditional tag to remove the footer widgets from other pages.
Note : The code will work in any Genesis child theme as long as its not already included in the theme.
Tested using the Outreach Pro child theme by StudioPress.
