Bought these because I was struggling with plantar fasciitis on one of my feet, probably caused by years of wearing dress shoes with little or no arch support. It's very comfortable and I don't need the orthotics in these slippers that I've used in my other slippers. Well made and very comfortable, these slippers provide the support you need to treat plantar fasciitis. Not a cure, but definitely a big help. It can get a bit warm in summer. They are a bit pricey but highly recommended based on the reviews I read online. I am very happy with the purchase.
