For years I have struggled to find slippers to wear around the house, take out the trash, etc. that have real arch support. I've worn a very popular Silicon Valley brand, if you know what I mean, but I've always been between sizes. Anyway, they finally seem to be getting the bill. They could have been a bit more stylish as they look a bit awkward on my feet. But they are VERY comfortable, especially with the softer insoles that come with the shoe. (The extra inserts are a nice bonus!) They're also quite warm, which comes in handy on cold winter days. Thanks very much!
