Very comfortable slippers! I bought these because I'm healing from plantar fasciitis & I needed to upgrade to some supportive slippers for walking around the house. These are perfect! They have excellent arch support and they are supportive and stable but still very comfortable. The wool is thick and seems durable and I like the hard sole for walking around outside. They do run small though. I usually wear a 9 or 9.5 in shoes. I ordered a size 10 (their size 41) and they fit perfectly. Definitely order the next size up if you're a half size. Very happy with this purchase.
