No complaints so far!
I've only had these slippers for a couple of weeks, but they're great, so far. Warm and sturdy. To perfect this shoe, the collapsible heel fabric could be softer/less noticeable when it's under the heel and being used as proper slippers/slip-ons. As it is now, it can be a bit annoying if you don't flip the heel up and wear as a proper shoe (you can feel the bump of the edging/stitching under your heel). Might also be nicer as slippers if there were cushy memory foam insoles, but I'm expecting these to last some time, so don't mind them being a bit harder.
