Adidas Predator Powerswerve rugby boots XTRX SG. These new Adidas Predator Powerswerve rugby boots are the stunning XTRX SG Special that can be seen on the feet of top rugby stars such as Johnny Wilkinson and Chris Paterson. FIFA compliant so that they can be worn on the football pitch at all levels also, the Adidas Predator Powerswerve rugby boots have been altered slightly to better meet the needs of todays rugby player. As well as the Adidas Predator technology that can be found in the same areas as all the boots from this range, the Vamp technology on the forefoot has been extended to the foldover tongue to enhance the contact made with rugby balls further. The last of the boot has been widened to better accomodate the larger grip and comfort required by rugby players, something which will benefit footballers with wider feet! The sole of the Adidas rugby boot comes with Adidas' XTRX SG sole and features Hybrid, round tipped studs which must be worn for rugby purposes and offer greater levels of traction. All other features of the Adidas Predator Powerswerve rugby boot can be found in its football version, including Dynamic PowerPulse weighted inserts, and external heel counter and off-set lacing.
