I've worn Ugg slides for years but finally got fed up with the hard footbed and the width. I had a tendency to walk right out of them. I have a pair of Acorn spa thong slippers that I love in spring, but needed a pair that would work either with bare feet or heavy socks. The footbed is very soft and well-cushioned, and it's stable. I tried on many pairs of foam-soled slippers and found that most of them caused my feet to tilt off to one side or the other, making them really unstable for walking around the house. My feet sit flat and centered on these.

They have a non-slip rubber outsole and I'm pleased that the "teeth" on the velcro are on the lower flap, where it won't snag on my socks. Barefoot, I wear them with the tabs fully overlapped, as shown in the picture. They fit snugly. I have narrow (A) feet and find it especially nice that even with my legs crossed and one foot dangling, they stay secure. Barefoot, I wear them with the tabs fully overlapped, as shown in the photo. I adjust it out a bit for socks, and it stays where I place it. If they do stretch out, I can adjust them to fit tighter.

I wear a size 10 and ordered the large in French Blue, which I'm happy to say is not as bright as shown. They're just a teensy bit shorter than I'd prefer, but overall are preferable to a pair that's too large, as the XL would be. I've got about 1/4" clearance at both toe and heel, adequate but not ideal. I'm ordering a pair in size XL for my mother, who wears a size 11 AA. She'll be thrilled to have slippers that don't fall off her feet.

Overall, these are well-designed slippers. Highly recommend.
