N°21 teamed up with design company Kartell, 2015.
Alessandro Dell’Acqua, founder and creative director of the Milanese upper contemporary brand, designed a flat sandal featuring a chunky sole and a feminine bow. In keeping with Kartell’s core business, the sandal called 'Knot' is realized using plastic in a glossy variation for the knot, while the sole has a mat finishing. The shoe style is available in five colors: black, powder pink, mustard yellow, khaki green and burgundy.
Dell’Acqua: 'It was challenging to recreate the knot using a material like plastic. All the knots are made by hand and Kartell showed to have the best technical skills to realize a product which looks beautiful.'
