I've tried a ton of slippers in the past and they're either not breathable enough (feet get sweaty), too flimsy, or they just break down quickly. These are on the pricier side, but they definitely check all the boxes on comfortable, warm slippers that won't break down (size up maybe half a size compared to your shoe size!) The leather bottom pair is also great for hardwood floors -- just enough grip to not be slippery, but also won't damage/scuff floors.
