Because Skins has no website to promote to. It's been "coming soon" for what, a month now? And if you believe (as I do) that the main purpose of the ad is for the company, aka, its stock, then it really doesn't matter what site you are directed to.
Many manufacturers advertise their products by promoting sales locations- it only makes sense, especially when you have no internal sales capability.
And footwearetc. has NO exclusivity on Skins. It's on Amazon for goodness sake.
Sorry, but I don't accept that of all the potential venues for selling shoes or directing traffic, Skins and/or footwearetc decided that ihub provided the best bang for the buck in terms of PRODUCT sales.
