For me it is barefoot in the summer, socks during spring and fall and slippers in the winter.
I'm exactly the same way - barefoot and flip flop slippers in summer, socks and warmer slippers in fall, winter and spring.In the summer I wear "flip flop" style slippers and any other time it's fuzzy socks AND slippers.
But washing feet is so much easier than getting it out of fabric.Since I've managed to step in cat vomit more than once, I would never go barefoot around the house.
That's why my slippers always have a waterproof sole.But washing feet is so much easier than getting it out of fabric.
