I'm trying to learn a little Blender and I downloaded the [Rain v2 model](https://cloud.blender.org/p/characters/5f04a68bb5f1a2612f7b29da) to experiment. It appears to be a fantastically well-outfitted model, however there's some basic stuff I don't understand. When I disable the scarf, for example, there's the body mesh underneath but when I disable the shoes, it appears as if there's nothing there even though I can see in edit mode that there's a full body mesh. Deleting the shoes doesn't make any difference.

Is the hidden part masked somehow, or hidden? How do I disable this?
