For sure this is true Keeping your shoes out of the house or else Lakshmi will go away!
How?

Well everytime you walk out of your homes your footwear is hungrily lapping up all the germs, bacteria, spores, virus from dirt, dried spit, dried animal dung, rainwater spreading bacteria and virus from drains to roads… And when you come home, you bring all that millions of germs under your feet!

Choice is yours to simply leave your footwear out of the house or at least near the entrance or bring them into your living room.

These germs will make someone sick in the family and you have to spend money for the treatment. In almost all South Indian homes, the foot wears never see the living room ever and that is a very healthy way to keep your Lakshmi within your own safe.

So start following this great habit not out of superstition but because it is healthy.
