Todd Schmalhurstwrote a review of Thule Rapid Crossroad Railing Foot Pack on January 16, 2011
These feet work great to hold the Thule Aero bars. I've got them on factory side rails for a 2010 Jeep Liberty. The strap grips the side rail very securely. Very easy to install.
Remember to protect your investment and get 4 SKS lock cylinders
