Hunter Boot enjoyed a boost in sales of 120% last year, helped by improved distribution, a broader range of products and global expansion.
The news comes four years after the brand, best known for its wellington boots, had to be rescued from administration.
Group revenue reached £56.4million in the year ended December 31, 2010 - up from £25.7million in 2009. Pre-tax profits totalled £16million.
The company’s turnaround happened in 2006 when it was bought by a consortium including Pentland and Conservative party donor Lord Marland.
Chairman Peter Mullen said the upturn in sales was down to better distribution, global expansion and a broader range of products, according to The Sunday Times.
Sales in the US went up 198% last year, according to documents to be filed at Companies House.
