make a running shoe cake? We have a group called Run the Streets that work with kids who have committed crimes. It is trying to get them back on the right path by running in marathons. They are having a dinner and I would like to donate a cake but I've recently inherited my 2 granddaughters after their stepmother abused them and am pretty busy. I know that some of you have done this cake and I've looked at pictures but I need to know about how long would it take to do this. I'm feeling pretty overwhelmed as is and don't want to over extend myself but I do want to make something nice for this group.
