Footwear retailer Dune has posted a “buoyant” Christmas, reporting a 10.6% jump in like-for-like sales over the six weeks ended January 3.

Online drove the increase, as ecommerce sales soared 55% over the period. Margin remained strong and in line with the same period the prior year.

Dune had its largest trading week in its history during Black Friday with “truly exceptional demand” despite promotions being the same as the previous year. The footwear retailer emphasised that the discounting did not affect Christmas trade, “which remained buoyant, helped by the colder weather which drove strong boot sales”.

Over the 2013/14 financial year, EBITDA increased 74% to £7.5m.

Dune executive chairman Daniel Rubin said: “This strong growth has continued into the current year”.

The company’s wholesale business has more than doubled, with its Imperia espadrille style, often worn by the Duchess of Cambridge, being a particular hit with US and Canadian customers.

Rubin added: “Women’s insatiable appetite for shoes and bags shows no sign of diminishing and now men are getting in on the act, becoming increasingly more adventurous in their footwear.”
