One of the greatest creators of his time, Pharrell Williams is challenging those who buy his "Human Race" adidas NMD sneakers to make them their own.

Williams shared his customized pair on Instagram earlier today, adding the caption, "Customized mine, How will you customize yours?" By customizing, Williams is referring to the stitch bordering the "Hu" lettering along the vamp.

The "Human Race" NMD run began with this week's yellow-based colorway, which is selling out at stores worldwide. There isn't yet a release date for the green colorway pictured above, but it is expected to drop soon.
