From Upscale Hype:

R&B singer Usher, who is overseas promoting his album, was seen being mobbed by fans in a Comme des Garcons Homme Plus cardigan ($960) in olive green, and Marc Jacobs M2588 sneakers ($570) in navy. The wool cardigan features plaid panels and multi-colored knit patched pockets. And the Marc Jacobs sneakers showcase zipper detailing running along the sides and around the top. What really sets these sneakers apart is the fact that they can be worn with or without the top portion, or with the tongue flap hanging down.
