Featuring comfort, control, and style that only Vans can offer, the Aura Pro delivers on its versatile, hardworking reputation as the boot built to perform in all environments. A dual-zone BOA Fit System featuring Vans Custom Focus provides unlimited on-the-fly micro-adjustability backed by the customizable comfort and heel hold of the Custom Slide Guide. Add in the V2 UltraCush Smartwool liner and V2 Waffle Pro outsole, and the Aura Pro will exceed your expectations of comfort and performance. It is normal for V-Series liners to fit snug right out of the box. After several hours of use, the dual-density, heat-moldable core of the liner will begin to shape to your foot, creating unparalleled comfort and a uniquely perfect fit. We recommend that you purchase your regular size.
