One of the team favorites that most freestyle riders enjoy. The BFB has a medium flex with a high response that is perfect for hitting those park runs or when making your own freestyle runs on the mountain. This boot is designed with a new QuadFit Liner providing exceptional customized comfort and support for your ankle. It now has stainless steel hooks and frictionless metal D-ring...
Sweet style, capital comfort, first-class fit, with a pleasing price to top it off. If that sounds appealing than the all new 07-08 women’s Mantra is the boot for you. A new self molding-liner, women’s specific pleasure cuff, and Vans’ own Pro-Flex Snowaffle outsole make this boot a great choice for any girl looking to up her game.
