There is a version of the black slipper that looks like it wandered in from a retirement home. Flat, shapeless, with a sole that gives up before you’ve even left the house. And then there is the other kind, the kind that sits low and clean on the foot, with a proper last and leather or suede that has some weight to it. The gap between those two things is enormous and the price difference is often smaller than you’d expect.

We’ve been looking specifically at slippers that could pass for something considerably more expensive than their tag suggests. The kind you’d wear to answer the door without a second thought, or push into a loafer at the last minute for something smart casual. Toe shape matters. So does the insole. A thin lining ruins everything. The ones we’ve pulled together here have the proportions right and the materials honest. They look like they cost more. That is the whole point.
