That completely depends on time, place, temperature and whether or not I have/had anywhere to go that day. Though I'm positive I have been wearing socks more often than not.

How hot does it get in Belgium?

At home, always barefeet. Even if I don´t have carpets at home (they´re a nightmare to clean).

Ah, and for the question.... in my country, most families don´t care about using shoes inside their houses. I personally don´t like it and when I have guests, I always provide them some flip-flops or slippers.

If I visit someone and the person/family offers a slipper, I´ll gladly take my shoes off.

I'm wearing what Americans call a Flip-Flop, though sometimes go bare feet just to feel the chill of the floor, feels relaxing.

Foot fetish > sock fetish

But coming to think about it

Dirty sock fetish > foot fetish > sock fetish

The stuff I miss most about the Wii was wonderful bullshit like this. Wii had a lot charm to it despite it's flaws.

During heat waves it's often several days over 30 degrees. The hottest days of the year are usually 32-34 degrees.

I don't like litter in my feet.

Is that all.
In a heat wave.

That is kind of, cool.

30 degrees is already waaay too hot for me. I guess I'm lucky I don't live in a country where it's superhot whole the time and where people don't even wear socks.
