The 27-year-old Newtownards woman was third in her heat in a time of 11.57 seconds into a slight head wind.
That was outside her own Irish record of 11.40 and the Rio Olympic Games qualifying standard of 11.32.
Should Foster fail to make the final, Friday's race will be her last chance to attain the Olympic qualifying mark.

Meanwhile Ireland's Marcus Lawler has qualified for the semi-final of the men's 200 metres.
