I walk on ceramic tiles all day so my feet get uncomfortable with regular house slippers.  I bought these because the picture looks like it has a nice thick sole and I thought they were cute.  I purchased an 8 W but I normally do not do that in house slippers.

When the slippers arrived the left inside sole was uneven and a bit uncomfortable.  But I wore them for a few more days to see what gives.  What gives is that the sole material molds to the shape of your foot.  They are warm, fit comfortably and are cute to boot.  So I bought another pair without the dip in the back heel.  They are a bit more inconvenient because you can't scoot into the shoe and run but they are warmer with the fur around the top.

Would I buy these again?  Yes,  I have two pair and would not hesitate to purchase more in the future.
