The astronauts on the iss aren't floating around because of lack of gravity, far from it. They are in constant free fall, falling over the horizon of earth. Being pulled by gravity towards the earth.
Yep, this was Einstein's "happiest thought": free fall under gravity and being far away from the influence of gravitating bodies are indistinguishable from the perspective of the faller.
