I purchased these slippers for my husband several weeks ago from Amazon for the southern hemisphere winter. The product is beautifully constructed, the materials excellent and seem to be very robust.  One caution - I should have taken more notice of reviewers who comment on size.  My husband takes a US 10.5 comfortably therefore I believed size 11 would be fine.  Not so.  I should have bought size 12.  He is still trying to 'break them in'.  Apart from care with size, I have no hesitation in recommending this product to anyone requiring a comfortable house slipper of excellent quality.
