You've had a wonderful day in the great outdoors, and after winding down in front of a nice camp fire, it is time to go to bed.
The only problem is... you've been staring at a damn campfire, so your night vision is shot, and you left your flashlight in the tent.
Fear not. The soles of your hiking
boots have been impregnated with strontium aluminate, and with them propped up in front of that roaring fire, they'll be bright as day by now. The green glow from underfoot will last plenty long enough to get you where you need to be, and the shining light will be directed exactly where it needs to be: onto where your next step will be. Once in the tent, you can flip the shoes sidways to get ready for bed, or leave them flat to "turn off" the light.
Want to go green? Fine, do away with all those toxic batteries. Want to go light? Fine, no need to carry such a heavy flashlight any more.
We're... umm... still working on what to do about caked-on mud, and soles wearing down on the trails...
glow-in-the-dark footwear is baked...

A short stroll around a certain nuclear power plant ought to charge them up for a few years. (where have you been [y_r_x]?) + |

great for seeing if something has crept into 'em |

Eh. I've been out of ideas for a while. |
|
| |
I fear that firelight won't charge glow in the dark pigments, as the wavelengths of the photons are too long. I just did a quick test, and found that bright red LED light doesn't charge a glow in the dark star at all, but white LED light does. |

So, burn something in your campfire that burns hotter than wood. |
|
| |
the stuff is excited at 200-450nm |
|
| |
...which confirms my suspicions. A wood fire emits essentially zero photons shorter than 450nm. |

Glow-in-the-dark Hiking Boots: making it easier for bears to find a midnight snack since 2011! |

If your hiking boots glow in the dark, aren't you in danger of
mistaking them for scorpions? Or even worse, vice versa. |
