Namaste Vinayaka
I do not like carpets. Why? Because very tiny carpet mites live in there. They can get you even sick, or contribute to breathing problems. Also, we may be sitting on life forms thus building bad karma (maybe... I might be taking this to an extreme Jain Dharma level which sometimes I do that, sorry)...
So stone is very clean. Tile too... I love the feel of stone or tile to barefeet. In fact, I tile a lot of things, using normal tiles or cut stone. Parts of my interior of the house, I tiled over myself. I plan on taking out the remaining carpet, I hate it.
Temples with stone or tile floors feel holy. They just do. I think the power of the murtis or even past events of the Gods in the temple cuts "grooves" into the stone, waves, which if a "cosmic needle" touches these "cuts" it plays back like a record player. Stone can also be a residence of Divinity, as so trees and water (wells, etc.).
I like temples with stone floor, holy wells, holy trees and plants. I like temples that "breath" (e.g. let outside air in).
I like crowdef temples and the sound of feet on stone.
