The wellington boot brand is a favourite of music festival goers while high-profile figures ranging from model Kate Moss to footballer Wayne Rooney have been spotted wearing it.
Accounts filed at Companies House show turnover at Hunter, which transferred manufacturing from Dumfries to China in 2007 but retains its registered office in Edinburgh, dipped from £78m to £74.4m in 2012.
UK sales fell from £36.3m to around £32.1m while the US dropped from £25.1m to £21.1m and Europe went down from £9.5m to £7.8m.
However, there were revenue gains in Canada, up from £1.5m to almost £5.4m, while turnover from the rest of the world grew from £5.5m to more than £8m.
Distribution costs increased from £3.4m to £4.3m while administrative expenses soared 47% from £13.1m to £19.3m.
Average staff numbers went up from 73 to 85 which saw employee costs go from £4.1m to more than £5.1m.
James Seuss, chief executive, said: "During the year, we continued to advance our plans to develop Hunter into a leading global lifestyle brand.
"Significant investments were made in people, products and distribution infrastructure to support this new brand direction for Hunter. This led, as expected, to an increase in operating expenses disproportionate to sales."
Investments included an e-commerce shop, a push into Canada, controlling distribution more tightly and the launch of a dedicated US website. The company is also understood to be planning a flagship store in London.
Hunter, founded in Edinburgh in 1857, is controlled by US private equity firm Searchlight Capital Partners.
