They have exceeded all expectations. The fit is great! I had felted wool slippers that flapped over my feet and gave off a huge amount of fiber balls, these things hugged my feet and shed very little even after a few weeks of wearing. The low back style can sometimes be a problem with slippers when your feet slip a little and your heel touches that edge (aye). However, with them, the back rises high enough to wrap around my heel and keep the slippers in place. They were comfortable from day one and the fit has only gotten better over time. The sole is made of thick leather, well stitched with the slippers. The lining on the sole is perfect for my needs. Not too soft, but with some recoil. They're warm, but my feet don't feel suffocating. And the fur doesn't itch at all. Great slippers!
