Johansson and Panettiere design shoes for charity

Olivia Palermo and Michelle Trachtenberg have also teamed up with style guru Stuart Weitzman for the special range, which will be sold to fund studies into ovarian cancer at the Folkman Institute in Boston, Massachusetts.

Johansson created a red patent platform, Panettiere designed a black suede ankle boot and Gossip Girl star Trachtenberg’s calf skin pumps feature stud detailing.

The shoes, along with Palermo’s satin sandals, will go on sale later this month (Aug11) and are priced from $425 (£265).
