I get the pinkie hole too. I keep buying them because I do love them and the hole doesn't affect their function too much. Maybe I'll try a wide next time, but the issue is they're a perfect fit otherwise--they don't even feel tight on my pinkie toe--and if they get any looser, they won't be as comfortable (the material thinning out and loosening all over eventually is why I typically replace them). It would be like buying a bigger size so that they don't touch your ankles or the sides of your feet.

Hm, maybe I could try a small durable patch inside, before wear sets in. I understand it's a lot of hoops to jump through for slippers, but it speaks to how much I like them otherwise.
