How do you turn these things on...?

Yesterday, I bought Mason a new pair of tennis shoes. They were red and black and very boyish. When Mason saw them, he was excited. He told me he liked them cause they were the school colors and that they were going to make him run really fast. Today, as I was walking Mason to the front door of school, He informed me that his shoes were broken. Through the giggles I asked why he thought that. He said he couldn't figure out how to turn the shoes on so he could run fast.
Maybe the shoe company should make the power button more accessible!
