CCDN 231- Concept ideas for my slippers

Research for my slippers- I have been researching into different images for my 231 to help with the design side to it. An inspiration to my design side is the look of these Japanese slippers. The slippers here are covering the whole foot and am liking the fact ti covers over the ankle piece too to add a bit more protection to my design.

I think that to make the inside much more softer I will still need to add more into it, but am looking at new possibilities into what to add inside.
