Query: Nice, but not built to last.

I've owned this pair of slippers for approx. two months now. They're very comfortable, easy to slip in and out of and keep my feet very warm. However, they haven't held up very well. I've only worn them around the house, indoors--nothing extreme or out of the ordinary. The padding on the inside bottom lining became flat and as hard as the sole of the shoe after about a month. Now another month later, the inside lining is starting to strip and come off the shoe. They were nice at first, but had I known this would happen I wouldn't have spent them money on them.
