Founded by the Antonini brothers, the company was born in 1983 with a retail spirit. The story began with 10 stores, followed by 3A’s first Nike reseller agreement — Nike then chose 3A as its official distributor. This allowed the company to bring Nike Inc.’s philosophy to Italy, later adding the exclusive distribution of the Nike Swim line. In 2017, 3A took over distribution from the Haddad Group, a US multinational, for Nike apparel aged 0–7 and Jordan, Hurley and Converse apparel aged 0–16, along with Converse hosiery collections with the Delta Galil group. 3A then signed an agreement with PVH for Tommy Hilfiger, Calvin Klein and Nike underwear, beachwear and accessories. In 2022, 3A became the Italian distributor of Crep Protect, a must-have brand in sneaker care. In 2023, 3A entered the German and French markets distributing Michael Kors menswear, and that same year took on distribution of Hurley and Ben Sherman in Italy. Since 2025, 3A has also distributed Converse footwear and the brands Clarks, Bape, Lacoste Kids and Nike ACG Kids.
