Barefoot. I always kick my shoes off when I can...at church, in my classroom and definitely at home. However, while we were in the States during winter, I did wear fuzzy, comfy house shoes because my feet were so cold all the time.
I prefer barefoot but have had to wear tennis shoes due to constant foot pain. I hate having my feet covered too...but they do get chilly in the winter so thick socks if I am not wearing shoes
I love being barefoot, but we have cement floors that can be hard on the joints.
In the summer I'm barefoot or have flip flops on (yes, in the house...cement floors, remember?). In winter, I usually have some light slippers on. But, with hot flashes, I end up barefoot more often than not.
Slippers during the winter and cold days (with socks if it's very cold) and barefoot the rest of the time. I can't stand wearing shoes inside the house. My one exception is if we have company - then I wear some type of shoe or flip flop.
