Over the weekend, Sneaker News showed you a pecular sample that combined a familiar Air Tech Challenge upper design and a visible-Air skate-like midsole. Here’s a look at another colorway of the unreleased sample in grey, blue, black and white; the midsole features circumventing stitching as well as vertical grooves on the toe, and the slightly wider base makes you think more ‘skate’ and less ‘tennis’. With two known colorways of this unreleased hybrid sample, perhaps it was on the verge of production. Will any more colorways pop up? Check out the detailed shots after the jump and let us know if you’d consider buying a pair if these released. In fact, you can snag this unreleased sample pair from oregonsole on eBay.
