For probably 25 years I've been wearing a similar style made by a sheepskin outfit in my town. I would replace them every two or three years. When I found these Overland Lily style slippers, I decided to give them a try. They arrived extremely quickly and double boxed, so I'm happy about that. They are beautifully made and oh so deliciously comfortable. The lining is thick and cozy. The soft sole seems more cushioned than my old slippers, and the soles are not slippery on my wood floors. I got the dark grey color, which is beautiful and won't show smudges or spots as much as the lighter colors would. Now for fit: I have a medium width foot, and wear an 8 most of the time and sometimes an 8.5 in boots. I ordered the size 8 and they are perfect for my foot. Comfortably snug in the beginning, but from past experience I know they will get looser as I wear them. Since it's winter and I live in the mountains, I need to wear socks all winter....I usually wear the Smartwool type wool socks and they are somewhat thick, but not hugely so. This size 8 is perfect with the socks. So I've become a fan of this Lily style slipper, and it's definitely far superior to the slippers I've had before from my local store. These are more expensive so I have high hopes that they hold up well, but I obviously can't comment on that so early on. Highly recommended.
