adidas Kakari Elite SG Rugby Boots Engineered to dominate, the Kakari Elite SG rugby boots are lighter than their predecessors to promote dynamic forward play. The sleek silhouette has been crafted with soft, synthetic leather which helps lock the foot in place and an inner strap provides essential support. The boots have strategically placed studs to deliver powerful traction as well as allowing you to move with speed and the adidas branding completes the design.
