The new Serfas Zirconium road bike shoe takes the top spot in their lineup, using more carbon fiber to shave weight.
A stiff carbon composite sole with matte carbon weave finish is matched up with a carbon reinforced heel that replaces a traditional heel cup to bring the shoes down to 275g (42). Uppers are microfiber and use a three strap system, with the main one getting a new, lighter ratchet system. Ventilation comes from a combo of mesh panels and holes, and the toe box is wide to allow your piggies to breathe a bit.
It’ll be available in black or white, and in a women’s specific design that has thinner straps. Men sizes: 42-49, Women: 36-42. Retail is $180, coming September.
