Boot brand Dr Martens has today posted a higher first-half profit, but warned that shipping delays in its US business due to wider supply chain troubles will continue into the next fiscal year.

It still reported a 44% increase in half yearly revenues in the Americas.

But it said that sales in countries like Japan, China and Australia continued to be impacted by pandemic-related restrictions.

The company, known for its chunky boots with yellow stitching, said pretax profit jumped 46% to £61.3m for the six months ended September 30.

Revenue rose 16% to £369.9m.

"We have seen more positive weeks than negative weeks (in the first half) for our like-for-like stores in UK and USA, led by growing footfall and better conversion," Dr. Martens boss Kenny Wilson said.

The company, which made its stock market debut in London earlier this year, also said it plans to open 20 to 25 new stores in fiscal year 2022, adding to its 135 existing stores.

Dr Martens also reiterated its confidence in achieving market expectations for fiscal year 2022, assuming there are no country-wide lockdowns.
