adidas Dyes Its Boost Sole in Red for This Upcoming Ultra Boost Uncaged

We previewed the as-yet-unreleased adidas Ultra Boost Uncaged sneaker with a red Primeknit upper last month, but now the Three Stripes has gone all out and dyed the the Boost midsole in a shade of blood red as well. The result is an instant head-turner, as this is one of the few instances where we have seen adidas dye the normally white Boost technology. Definitely not one for the faint of heart, keep checking back for release details for this ominous rendition of the adidas Ultra Boost Uncaged.
