Full page width with woocommerce and twenty fourteen theme

Hi everyone!

I have a wordpress with a twenty fourteen theme and an installed woocommerce. My problem is that I´m not able to set up so it uses the full width of the pages… I have a big space on the left and right side of the woocommerce content…

Everything I tried was not successful. Do you have an idea what to do?

Thanks!
