We wear shoe covers for various reasons. Sometimes, it's because it's a little chilly out, and other times, we're simply trying to eke out every aerodynamic advantage that we can muster. But, we have to admit that it's increasingly rare to find shoe covers that fulfill both roles. Fortunately, we discovered the Capo Crono Lycra Shoe Covers. Capo's Crono Lycra shoe covers are constructed from the Power Lycra material. More than just an authoritative name, it's also an authoritative fabric. Like its brother, Power Lycra is extremely breathable and aerodynamic. However, the advantages of Power encompass the worlds of support, precise fit, and movement. Basically, this fabric conforms to the shape of your foot to provide the ultimate in aerodynamic advantage. All the while, the material is supporting a light insulation layer that warms on cool days, yet cools on warm days. It's not sorcery, it's just good design. For fit, Capo relied on its tried and true Block System for the entryexit point. This system reinforces the rear zipper and heel cup by strengthening the seams that its connected to. On top of that, the Crono follows a minimally seamed design that flows with the natural contours of your foot. The Capo Lycra Shoe Covers are available in the color Black and White and in five sizes from Small to XX Large. Given the breathability of the fabric, Capo suggests that these covers are appropriate for use in all weather conditions.
