Giro Empire SLX II Shoe The shoe that redefined laces, refined again The Giro Empire SLX II is the latest evolution of the shoe that put lace-up road cycling footwear on the map. An all-new flat knitted Synchwire(TM) upper combines the lowest possible weight with exceptional breathability, building ventilation directly into the knitted mesh construction and reinforcing durability via a thermally bonded TPU skin - all without a single seam. Seven classically-positioned lace eyelets deliver unmatched comfort and conformity around the foot, while an all-new unidirectional forged carbon fiber outsole plate - 20Nm stiffer than the previous version - drives power through every pedal stroke. At just 221g for size 43, the Empire SLX II is proof that laces still reign.
