Vans Classic Slip On - Boys' Infant The Vans Classic Slip-On needs no introduction. It's a legendary shoe made with a simple design and comfortable style. The variety of colors and patterns on the canvas upper allow you to express yourself - buy a pair for each day of the week! There's a padded collar and footbed, cotton drill lining and a vulcanized sole attachment. The style is completed with a traditional "Off The Wall" gum rubber sole that keeps your feet stuck firmly to your deck.
