The company's growth allowed it to develop larger facilities in 1928 occupying a city block in Buenos Aires' southside Barracas section. This facility began making vulcanized rubber sole shoes in the 1930s under the supervision of engineer Luis Pastorino.
Alpargatas relocated its manufacturing facilities to the southern suburb of Florencio Varela in 1950. This new, 70,000 m² (740,000 ft²) facility allowed it to diversify its product line, leading to the launching of Flecha, its casual footwear brand, in 1962. The establishment of a cotton gin in Sáenz Peña, a town in northern Argentina, allowed Alpargatas to manufacture denim in 1968, allowing it to take advantage to fashion trends in that direction, and a new plant in Aguilares, Tucumán, allowed it to create its Pampero children's footwear line in 1972.[4]
