This is a genuinely good point!

Not having said this could be OP’s problem, it’s a common problem, along with any kind of roughness on anyones feet.

📍I’ve got to add to this by saying that I’ve got restless leg (and feet) syndrome, which has caused my sheets excessive wear and tare the last several years. Nails being nicely trimmed, it’s still very likely to happen. When I finally realized that’s what caused my sheet problem it was such an “AHA moment” for me!
