first monofilament line (fishing line) buckle was created by SIDI in 1993,
revolutionizing shoe design with the first-ever precision closure system. The
latest version of that system, SIDI’s Techno II Buckle®, provides even pressure
distribution with fine-tooth ratchet adjustment of string tension, for
ultra-smooth adjustment that helps the shoe’s upper conform to the shape of the
foot for a customized fit.
