I have some Skechers slip-ins that I love. I live in Japan where you have to take off/put on shoes all the time at home, restuarants, doctors/dentists, gyms, etc, so they are incredibly convenient. Also very comfortable, and constructed about as well as a pair of Nikes costing twice as much.
I am unapologetically into Skechers. Though I do try to seek out the ones without that big ugly "S" on the side.
