We just checked out the Puma x Sonic RS-0 trainers which have just been unveiled at the RS-0 launch event in Berlin this week, and thanks to the fine folks over at Sega we were allowed to take the shoes out of their presentation box and snap a few shots.
The trainers are a prototype (albeit a final one), making them one of only a few pairs that currently exist. Mass production of the trainer isn't planned, but we have heard that there are going to be a few thousand pairs produced worldwide, and they'll be sold via different outlets and through various channels, and probably also given away as exclusive gifts.
That being the case it probably won't be easy to get your hands on a pair, and that's not even mentioning the price, which has yet to be confirmed but will no doubt reflect their rarity.
