The World Cup ’s just around the niche , and that means the shoe fellowship are now battling over who ’s stuff is more innovational . In a feat of high-pitched - technical school engineering , Adidas has made the light association football shoe ever .
Where the typical soccer shoe count about 10 ounces , the Adidas F50 Adizero tips in at 5.8 . It ’s a weird sensation to go through — picking them up finger like lifting a stack of chain armour . Crazy - light shoes , how do they work ?

fit in to Adidas ’s senior production manager , Aubrey Dolan , there ’s in reality a slew of high - tech discovery at work . “ you may always transfer material to make one lightweight sample , but mass - produce something for a aggregate grocery store that actually function is another challenge exclusively . ”
Almost all association football shoes have a unshakable insole board that keep them static . The F50 Adizero does n’t have that at all — rather it just has a molded poly - amide outsole they call a “ sprint inning . ” All the constancy comes from the tailfin running across the middle of the footprint :
These , in turn , are molded in carefully calibrated , organic shapes — if there were any sharp angles , the fillet of sole could really snap since it is , after all , just a thin slip of high - technical school charge plate . mutant in the anatomy and thickness of the frame — and the placement of the curving rib — allows flexibility in some position , such as the forefoot , and rigidness in the heel :
According to Dolan , the inspiration was modern - day cycling . “ In the wheel frame you see in the Tour de France , all the strength comes from the geometry itself . ”
And the upper of the shoe , which just seems like plastic - yttrium sheath , hide an intense process of materials technology . It ’s made of microfiber — that is , synthetic fibers that have be intertwined , which allow the materials engineers to dial in a precise combining of flex and rigidness . That way , you do n’t have to add together more textile to make interior supports , and you may even print additional support structure directly onto the brake shoe , which is n’t potential with your received leather :
But what insures that these backwash cars wo n’t vaporize apart when they ’re actually in use ? “ It ’s secure to say this is the most rigorously tested product we ’ve ever made , ” says Dolan . The shoes were put through stride on myriad players — pros and amateurs likewise — and the even tested in moth-eaten rooms and hot rooms , to ascertain they would n’t bankrupt down .
