"Our overall results reflect the impact of higher clearance sales as we made the decision in the quarter to increase our promotional cadence, given the overall retail environment," explained chief executive Gregg Ribatt. "While we still face foreign exchange headwinds from the stronger US dollar and macroeconomic challenges, we are making progress in our transformation efforts.
"I believe we are reaching an inflection point and we will see the benefits of our actions increasingly as 2016 progresses."
For its fourth quarter of 2015, the company performed roughly in-line with guidance, producing revenues of $208.7m, up seven per cent on a constant currency basis.
However, the footwear maker was still loss-making in its final quarter, with net losses attributable to shareholders of $73.9m, down further from the previous year's loss of $56.9m.
