Adidas Adizero Feather with Nike Courtballistec outsole?!

Here’s some very interesting pictures taken during the ATP World Tour Finals Pro locker sale. Checkout Jo Wilfred Tsonga’s custom Adidas Adizero Feather with a Nike Courtballistec 2.3 outsole. See the photo comparison with Nadal’s real shoe as well below. I guess Tsonga wanted the best of both world?

Well I hope that design isn’t patented! But definitely interesting! I too would prefer the Cb sole design on every shoe I own…
