text: I thought when I bought these they would be fleece lined, but they were not. Not sure what it's lined with, but it's sure not fuzzy, warm fleece. I ended up putting my orthotic in, followed by my boot insoles on top of that just to give my feet support & warmth. The outside of shoe & the sole are very good. But all they are are big, sloppy slippers. I kept them due to the price & my orthotics shored up the slippers.if u like sloppy soft slippers with no support, then these will do the trick
