They keep my feet and ankles warm, but I would not order another pair.

As others have warned, these slippers run very small. I thought a M/L would fit my size 8M feet OK, but my heels hang over the backs of the soles some, even with my toes pressed up against the stitching in front. No way would these fit bigger feet! Others have described the messy stitching, so I'll "ditto" that.

I suppose these slippers will stretch out in time (or perhaps just break apart) as they are very soft. If they fit better, I could give more stars. The sole material is not waterproofed at all, so if you step on anything damp, like the bath mat after your shower, you'll know it immediately. Squish! (Take away stars for that.) But for sitting around watching TV or reading on a cold, mid-west winter's evening, these slippers do the job.
