Here are the much coveted Sonic X Sneakers! They are for boys or girls, but (sadly) only came in kids sizes. They were released around the time of the show (but later on) and are still quite wanted just as a collectible, not even as a wearable item. (Too small for pretty much anyone) Why? because they're just JAMMED with super detail! First of all, they light up when you run (lights flash behind Sonic panel)

Then, there's Sonic detail at every turn. The box looks nice, with X logo, and 2 different Sonic arts. One side of the shoe (outer) has very shiny plastic 'jumping punch' Sonic, and the other side has a textured Knuckles portrait. But look at the background area for Knuckles: those aren't just dots, they're actually little tiny Sonic X logo heads. The top velcro has an X logo, the shoe tongue has a plastic Sonic face & the inside cushion layer also has an X logo. But the details don't stop there! 

The heels have a X head raised/soft silver 'button' disk set in them. The sole of the shoe has a full color X logo in a clear/shiny 'bubble' of plastic. (Why? This is a real nice item, but it would be the first thing to get scuffed away to nothing) The foot arch area also has a 'spikes' looking design going on. It's no wonder the shoes are so highly desired (they were 14.99 when new, as evidenced by circle price tag there) a lot of thought went into branding them completely Sonic X. It's too bad they were uncommon when new, and small sizes only. This pair is in the SonicGear personal collection. (As of 2017, the light up feature still works)
