Nine-month-old Emery Hope is among the babies crawling through a terrain of mock mountains and ski slopes Tuesday while their moms bid on shoes signed by celebrities including Tori Spelling.
The shoes are from the Big Movers collection, designed for parents on the go.
The event in a Manhattan park benefits the Washington nonprofit KaBOOM! which builds playgrounds.
Harmon's television credits include "Law & Order" and "Women's Murder Club." She kicks off the shoe auction with her husband, former New York Giants and St. Louis Rams football player Jason Sehorn.
