Kristen Stewart donated a signed pair of black Keds to the website Shoe Revolt. Shoe Revolt is combating human trafficking one sole at at time.

The ultimate goal is to build 51 shelters (one for each state and in D.C.) that will provide housing, mentoring, and counseling services to survivors of sexual exploitation.

The star joins other celebrities who have also donated to the site, including Sarah Jessica Parker and Zoe Bell.
