Just as the acquisition of Sanuk shoes by Deckers Outdoor Corporation was nearing completion, Deckers announced late last month that it was going to stop selling its Simple brand. Simple was one of the first brands of eco-conscious footwear, but Angel Martinez, chief executive and chairman at Deckers, noted that it had some overlap with Sanuk, and the new brand has a positive outlook and global appeal. The last Simple shoes will be distributed by Dec. 31. Deckers is paying $120 million plus earn-outs for Sanuk, which has sales of $43 million last year. The deal includes certain assets and liabilities of Sanuk U.S.A. and of C&C Partners, the exclusive licensee for the Sanuk brand in the United States, Europe and Canada. While Sanuk is growing very rapidly, Simple saw its sales decline by 28 percent to $6.0 million in the first quarter of this year.
