At just 185g per shoe, with pro-level performance and unmatched comfort, the Empire SLX lets you fly in first-class style. To create a minimalist shoe that retains the support structure of the legendary Empire while advancing style, we started with a one-piece ultra-light "Synchwire" monofilament mesh upper designed around a classic lace-up closure to fit and feel like a second skin. Heat sealed Teijin TPU adds structural support exactly where it's needed, and a high-modulus Easton EC90 SLX2 carbon fiber plate provides the ultimate stiffness-to-weight ratio for power transfer. Our SuperNatural Fit Adjustable Insole System is the final touch, allowing you to customize arch support right out of the box for luxurious comfort and optimal pedaling efficiency.
