This brand is so-so. The wool feels scratchy like synthetic. I buy a pair of lined slippers every year - I wear them out because I wear them almost year-round. I've tried most of the brands. The sheepskin lined cost more but are definitely better quality. I guess this one's ok at $15 but I certainly wouldn't pay more than that. My favorite is the Tamarac brand.  I wouldn't buy this brand again even at $15.
