What footwear (if any) do you wear at home?

In the house, slippers.  Outside, sneakers.

No shoes in the house. 

I wear a woolen slipper that my gal friend's momma knitted.

Inside I wear socks and flip-flops.  Outside I wear flip-flops or athletic shoes (depending on what I'm doing).  I'd prefer to go barefoot year round, but my super-sensitive feet won't allow that.

I wear flip-flops. 

Socks or barefoot. 

Unless I am going out and about in town. I only wear socks or slippers inside my apartment.

Gripper socks

Depends on the time of day.  In the morning, once I am dressed I will have tennis shoes on...or on weekends flipflops.  In the evening, after I am done for the day, I will take off my shoes and socks while I am on the couch.
