Dr. Martens on Tuesday posted a 61.3% jump in full-year adjusted pre-tax profit, as the British bootmaker began to see results from a tighter control on costs and fewer discounts. The company, known for its iconic lace-up chunky boots, has deliberately pulled back on clearance activity across its direct-to-consumer and wholesale channels to improve the quality of its sales. Dr. Martens posted adjusted pre-tax profit of 55 million pounds ($73.78 million) for the year ended March 29, up from the 34.1 million pounds posted last year, with shoes being the standout performer.
