I take all of my silicone toys with me. I wrap them in lint-free cloths and after I've packed everything else, I stuff them into the very top of the suitcase (it's one of those rolling, upright deals) and zip it up. That way if TSA gets a hair up their bum and want to know what they are, they are easily accessible and won't be crushed by clothing/bath and beauty products if they were on the bottom. And that's where the shoes go, anyway.
