These are without a doubt the best slippers I have ever owned. The quality of materials and workmanship are heads above slippers costing as much as twice as these. If fact These are so good I am purchasing a second pair to put up. It seems that when you find a good product they always seem to disappear. The real sheepskin are cool in the summer and I am sure they will be warm in the winter since this is the benefit of real sheepskin. The soles of these slippers provide great traction even on smooth wet concrete like my patio. I in my honest opinion you cannot go wrong purchasing these slippers. I would highly advise you to purchase 2 pair in the event that they me not be available at a later date. I have owned these for almost 3 months and have been outside, walked on my rought concrete sidewalk and the soles show absolutely no signes of wear. The minute I get home I remove my $120 Asic's Gel running shoes and put these slippers on. You cannot go wrong with a purchase of the fine men's slippers.
