Buckled Faux Shearling Lined Boot (Women)

I've had these boots for about 6 months, wearing them maybe once or twice a week to my very sedentary job, and they've completely fallen apart. They're definitely more like slipper boots than actual boots. The inner soles have flattened and slid around inside and the bottom of the boots is starting to completely detach on both of them. They were comfortable while they lasted, but should definitely be treated as slippers.
