What's the difference between sheepskin and lambs wool boot lining?

[Wenchelda]

Is one warmer than the other? I've got sheepskin lined uggs that are super cosy - how will boots with lambs wool lining compare? Thanks.

Not sure how they will compare for warmth and comfort, but I think lambswool lining is softer.

Thanks. It does sound like it would be soft and comfortable. But my feet are always freezing so need it to be warm too!
