Ballerini calls its Perfetta ballerina flats "the world's most comfortable ballerina flats" and they sure don't skimp on style either, which could really make them the most perfect flat, since there's usually a compromise on one or the other.
As much as flat shoes are supposed to be sensible, there's usually a breaking-in period where you're plagued with blisters, calluses, bandaids and feet that hurt. Ballerini's Perfetta line is specifically designed with padded lining and insoles, a flexible sole and extra support on stress points to prevent this.
Normally, ballerina flats of this quality would retail for $150, but they are now being offered as hand-signed editions on Kickstarter at a wholesale price. With its crowdfunding campaign, Ballerini will be able to launch production of the Perfetta line and establish itself as a company in Sao Paulo.
