I've never been one to wear much in the way of slippers, but having installed hardwood floors last spring, I figured with the coming winter cool weather, it would be a good idea to have something to wear around the house to keep my feet from getting too cold.  I have found that these lounge clogs are quite comfortable and keep my feet up off the cool wood floor just enough.  I don't feel any real "workout" from them, per se, nor do I notice any toning in my hips, thighs or buttocks, but this may just be because I am a physically active person.  Overall, these clogs are very comfortable, and well-insulated.  The construction is good, and the rubber sole enables me to walk outside briefly, if I have to, with little to no worry of ruining my slippers.  Overall, these were a great purchase at the sale price, and I would consider buying them again, if I had a similar opportunity and need.
