Ankle straps are smaller around the boot with a flex window for max agility while maintaining support. Toe straps are designed to be used as a toe cap, but also fit nicely as a traditional strap across the top of the boot. Ladders and adjusters produced in-house with unique thermoplastics that maintain flex over a wide temperature range Incorporates Burton's time-tested bomber buckles Fusion Molded Touring Brackets: One piece design combines bushings and bracket into a single piece, made entirely of a self lubricating bushing grade of plastic. Thanks to the improved material properties, the pivot holes in Fusion brackets last longer than the brass bushings in our previous aluminum style brackets. Moving to the molded design also reduced the weight of the bracket itself by 40%.
