Great Construction, worth it!
Excellent shoe cover. Before I bought this, I thought hard between the various Castelli choices, and I am very happy that I chose the Narcisista. It has the most detailed construction and it is well thought out. The zipper is great, very solid. The stretch is very nice. I purchased a L for my 43.5 and the fit is spot on. I used the covers on a mild morning, and they were excellent. A+ in my book, and im very happy to chose these over the other Castelli options.
