I was looking for some inexpensive house shoes with a substantial sole so I can go out doors on occasion. but must have a lining.- I was hoping for a more rigid sole, but these aren't too bad, it's just a rubber sole with some flex but a bit more stiff than some anyway.-Someone noted they run large, if so 1/2 size at best. I bought a 10 for a normally 10.5-11 shoe I wear. They are about right, just a touch tight but stretched easy with wear.-Your feet WILL SWEAT in these though. I have a leather punch so I punched a couple holes on either side of the arch and they are MUCH BETTER.-I rated a 4 of 5 as they are not expensive. If they were expensive I would have rated at a 3
