CASTELLI’S MOST VERSATILE BOOTIE.
Windproof to keep the cold off? Yep. Waterproof fabric? Yep. Super aerodynamic
for time trials? Got that one too. So the Castelli Nano Cycling Shoe Cover is
good for everything, but Castelli is tired of the “you could wear that to the
disco” jokes. It wasn’t that funny the first time.
Silicone-coated Lycra® is
stretchy and water proof
Keeps out the wind, cold
Highly aerodynamic so
it’s great for time trials
Heavy-duty YKK® zipper
Silicone elastic at cuff
