I usually go for a run nightly between 12pm and 2 am,

Perhaps it's a sign for super special running powers handed down by some amazing cross country runner or whatever, and can only be tapped if you try getting them during an electrical storm. You know, like what happened with Lil' Bow Wow when he was in the NBA. 

Recently the shoe disappeared and I thought nothing of it, there are lots of good reasons that could account for that. However last night it reappeared, WHAT THE FUCK.

This all sounds like some premise for a Stephen King novel.

" When I was growing up in New York, I saw Shoes tied on Electric wires all the time. Never knew what they meant. Heard multiple rumors though. Bad ones too. "

" @Jimbo: 
" Prehaps he simply put the shoe there himself after killing another runner he met at 1 in the morning. But he doesn't even remember doing it, he's the perfect killer.

Does England (I assume that's where the picture is from.) really have serious gangs problems? "

Also, the most obvious course of action now is to go into the resident evil mansion at night.

" You could not pay me in comic books or cold cash to go out running in my neighborhood between 12-2am. It's bad enough that the bums come sit on your porch when you're home in the middle of the day. "

" Yes, you are being sent a message.   Doesn't it mean that that area has a certain drug for sale? Like a certain shoe symbolizes what drug it is etc. "

Take a photo of the shoe next time you go for a run

Dude, it is a sign.
 
There's a single running shoe tied to a lamp post on my route home as well.
 
Dude.
