My old pair of Old Friend slippers finally wore out and I bought these to replace them.  The style is the same, but the new ones have an improved replaceable insole with added support, and I like it. The fleece is thick and soft, warm in the winter and not hot in the summer.

I see a lot of people complaining about the size.  What you have to be aware of is that when you first put them on as new, they will feel small because the sheepskin is very "fluffy".  But after you wear them a couple of times, they'll compress in the right places and feel much better.  I know that the product title says "Extra Wide" but that seems to be because wide widths are available.  Order the size and width you want.  I'd say that the size runs true once broken in.  Of course, check the size stamped on the bottom of the sole to make sure you got what you ordered.

I have tried many different brands of sheepskin slippers, and keep coming back to Old Friend.

After six years, the pair I bought in 2010 wore out so I bought a new pair. Just as nice as the old ones.
