Together with adidas, The Teenage Mutant Ninja Turtles keep the party going for their 40th anniversary with the incoming Adidas x TMNT SHELLTOE 'SPLINTER'. This time round, they pay homage to Master Splinter, the stoic sage and martial arts instructor of the reptilian superheroes. Taking on the silhouette of a classic ‘Shelltoe’ – more widely known as the Superstar – they feature furry brown suede uppers, frayed laces and deep red 3-stripes. Gold-tone ninja charms feature on the laces in a final tribute to the ninjutsu master himself.
