I 1750, tógadh monarcha bróg i Lean, Massachusetts, rud a d'fhorbair an teicneolaíocht áitiúil um dhéanamh bróg tuilleadh. Ann, ní dhéanann oibrithe bróga neamhspleácha a thuilleadh, agus tá gach nasc táirgeachta bróga i gceannas ar dhuine oilte. Tosaíonn an líne táirgeachta a fhoirmiú. Ar dtús bhí na bróga fós déanta in ord, ach chun na hoibrithe a choinneáil gnóthach sa tséasúr seo, thosaigh úinéir an tsiopa bróg ag déanamh bróga gan aon áirithintí. Tá na bróga seo, ar a dtugtar bróga ar díol, ar taispeáint i bhfuinneoga na siopaí áitiúla. Sna laethanta tosaigh, bhain na deartháireacha Harvey úsáid as carráistí chun bróga a lódáil le díol agus iad a dhíol in áiteanna in aice láimhe.
In 1793, they opened their first retail shoe store in Boston, selling finished shoes every Wednesday and Saturday. Since the middle of the eighteenth century, inventors have been working on the improvement of sewing machines. It was not until 1790 that the first sewing machine dedicated to leather processing was transformed by an Englishman named Thomas Saint. It's pretty much just an awl that goes straight up to punch holes in the leather. The British Sir Mark Brownler, who was the chief engineer of the New York Harbor, invented a press that used metal needles to sew the upper to the sole. In order to do his duty in Britain's war against Napoleon, with the help of disabled soldiers, Brownle produced 400 pairs of shoes a day. After the war, the British shoe industry returned to manual operations.
