Vans and Marc Jacobs will come together once again to design some very nice Slip Ons for Spring-Summer 2007. Vans and Marc Jacobs have collaborated on anything from Sk8-Hi’s to Chukkas, but this season will focus more on the Vans Slip Ons, which three pairs have been designed using canvas followed up by basic but nice colors. Expect them to release in the next couple of weeks, via Complex.
