They look like odd-shaped pillows but Innies are really a sachet/shape holder for your boots. Here’s one in action:
I’ve been testing these out – as I usually use plastic forms instead – and find them actually easier to use, less hard on the leather, and they have a nice light lavender scent which I am imagining also helps absorb odors.
They make a version for handbags, too. I haven’t used that one yet.
