MrCheeze's video: Do F Boots crash as adult on Wii U

Well yes, but actually no. On N64 and Wii, deku stick as adult crashes the game immediately, due to trying to draw invalid display lists. On Wii U, it doesn't crash at all. Turns out, the reason F boots crash as adult is also because of invalid display lists - adult link (but not child link) is coded to render whatever boots he's currently wearing. So it's natural to wonder if Wii U prevents this crash as well. Turns out, it does and it doesn't. Sometimes it crashes instantly, sometimes you can actually use them for a short period as shown in this video. But the game is extremely unstable in this state, so this isn't usable for any practical purpose.
