I have waited for years, tried many slippers and then had to return them. I need shoes with arch support as I have flat feet, underwire and a large width. Always have decent shoes. I wear Beast Brooks sneakers in the morning, afternoon and after bathing. What a relief to finally find slippers that I can wear all day without back or knee pain. I can't find anything supportive in wide women's shoes. Size 8 seems to help with the men's Vionic. These shoes are truly heaven sent. Ordered a second pair today. Won't be the last. I'm so thankful that I finally found something comfortable and quality.
