I DONT KNOW IF ARE THINGS OF MINE, BUT I HAVE MORE THAN 5 YEARS USING THIS STYLE,ADIDAS SAMOA, SO I THINK THIS SNEAKERS FROM THIS STORE ITS NO GENUINE 'CAUSE THE "LEATHER" ITS TOO HARD, BEFORE I BOUGHT THIS BLACK UNIT I HAD BOUGHT A WHITE ONE TO AMAZON STORE AND THOSE IF SEEMS TO BE GENUINE, LEATHER ITS VERY SOFT, BUYERS TAKE CARE WHO YOU BUY
