Weighing in at a ridiculously light 350g for the pair, the Empire SLX is an amazing 200g lighter than Giro’s Empire ACC – making it possibly the lightest road shoe available.
To save weight, Giro decided to use a new upper made from Teijin Evofibre SL. According to the Italian brand, the material is not only lighter, but makes for a more breathable shoe.
The new SLX carries over Easton’s EC90 SLXII high-modulus carbon fiber sole, which features the same low 6.5mm stack height, along with replaceable heel pads and titanium hardware.
However, beyond just an exercise in styling and light weight, the SLX is also a "reality" when it comes to performance as well.
Indeed, Giro says big name riders such as Bradley Wiggins and Taylor Phinney have turned to the SLX as their shoe of choice – the argument being that the lacing system makes for better comfort and adjustably as compared to the typical mechanical closure, racket system.
“From different lacing patterns to more incremental adjustment points, laces simply provide more range when it comes to fit, and the feel is more natural.”
“They’re also incredibly lightweight, easy to replace and hard to destroy in a crash.”
