Jordan Crawford's Shoes Are As Cold As Ice

In the past 30 minutes, I've learned so much about the reasoning for why Washington Wizards guard Jordan Crawford decided to tweet out a photo of a bunch of Nike Zoom KD IV shoes in his fridge. At first glance, the idea of someone keeping their shoes in the fridge makes no sense. Why would you put those by the food you're going to eat?

But maybe Crawford is actually smarter than all of us. Some possible explanations for why this photo exists:

1. This is actually a metaphor of sorts. Sneakerheads who are trying to save a pair of shoes to wear much later down the line say they're "putting them on ice." Maybe Crawford was taking this phrase very, very literally.
2. As weird as it may seem, wearing shoes that have been in the fridge for a while might actually feel pretty good. I've never done it, but I can't knock it until I try it.
3. It was a prank by one of his friends.
4. The shoes were actually worn recently, and this was a way to get rid of the odor. People do this often with clothes, but I'm not sure it's that common with footwear.

I'm leaning toward No. 3 personally, but it could be any of those things. Which one makes the most sense to you?
