The Mountain Course; legendary, iconic and one of the ultimate challenges in motorsports. 37 and a half miles of everyday street tarmac that snakes through stone-wall lined country lanes, along tree tunneled straights, through usually sleepy towns and over the foreboding mountain roads of the Isle of Man at full throttle. A rugged, windswept island setting that sits in the middle of the Irish Sea which, for over 110 years, has been the greatest test of rider and machine at the annual TT races. To complete the TT course is special, to win is to join a small group of motorcycle racing’s revered stars. With 23 TT victories in his career to date, John McGuinness is a legend; the King of the Mountain who has re-written the record books and stood on more TT podiums than any rider in history. His focus, his accuracy and his devasting speed has set a bench-mark that few can aspire to match and for such ability, it is fitting for Alpinestars to introduce the John McGuinness Limited Edition Supertech R Boot. The boot itself is the usual no-compromise boot you'd expect from Alpinestars. Designed and developed to the highest technical standards, the Supertech R Boots today represent the pinnacle of racing innovation for track and road use. Alpinestars’ most iconic sports boot, the Supertech R incorporates a whole host of performance innovations including a redesigned compound rubber sole, an ergonomically profiled shin plate, a redesigned front flex area, plus the pioneering dual torsion, bio-mechanical ankle brace – all of which enhance this CE certified boot.
