Once again, Castelli improves upon a proven design that brings it to the next level. In the case of the Poggia 4 Shoe Cover, more stretch was added to enhance fit and aerodynamics, while making it easier to put on over your shoe.

The main body panel has a PU-coated windproof & waterproof exterior with completely sealed seams. It has some elasticity, so the fit around the shoe is nice and snug with little to no bunching or gathering of fabric. The top cuff of the shoe cover features Castelli's Nanoflex fabric which is DWR water proofed and has a comfortable and warm slight fleece lining. Sealed side zipper is a clever way of providing shoe and buckle access. It also makes putting the Poggia on or taking it off a snap. Reflective piping and a rear pull tab round out the design.
