Slingshots newly updated closure system is just one of the many things to love about the new and improved 2014 Jewel boot. It means less time fiddling with tangled laces and more time doing what you do best: riding! With the HHD System the fit is completely custom with upper and lower zone tuning as well as heat formable liners. Coupled with the bottomless base system, riders will experience the ultimate feeling of boot to board connectivity. Polish it off with the ergonomic footbeds and kiss your old boots goodbye.
