It turns out this year's retro run of Nike Air Penny 2s includes GS-exclusives.
The only one that's arrived so far is this pair, which has urban lilac shades mixed into its black and white base. 2016's colorways of this shoe have so far adhered to traditional Penny colors, but it makes sense that the GS range would be allowed to go beyond that.
While there's no sneaker release date for these, they're already showing up at Nike accounts, so keep your eyes peeled.
