Durex-to-Scholl group SSL International was yesterday lifted by strong demand for its Party Feet cushioned shoe inserts as it reported a 25 per cent rise in operating profits.

The group said the European launch of Party Feet --which help prevent pain in the feet from wearing high heels --was a main driver behind an 18.6 per cent increase in Scholl footcare sales.

Improved sales of both Scholl and its range of Durex condoms contributed to operating profits of £24.1 million in the six months to September 30 and left the group confident of hitting its financial targets.

Chief executive Garry Watts said: "This is a strong first half performance driven by the growth of Durex and Scholl footwear."

He said the firm was "well on track" to hit its target of doubling operating profits to £52 million by March 2007 while investing in the development of brands.

The firm said investment in new products was the key to the future of Scholl footcare, and it was currently working on products including an improved treatment for cracked heels, a wart remover and a foot skincare mousse.

However Scholl footwear sales fell by 9.4 per cent to £27.8 million, although the firm said there were " encouraging signs" for its key spring/summer ranges.

SSL recently launched the more modern ranges into upmarket department stores such as Selfridges and high street chains Schuh and Office in a bid to reverse flagging sales.

Durex sales increased by almost ten per cent to £77.1 million as the brand increased its global market share to more than 30 per cent, with significant growth in the US and Eastern Europe. This included strong demand for its Durex Play lubricants and devices range.

Mr Watts said US demand had gone " absolutely gangbuster".

He added: "It's a real powerhouse."

And it would remain so for the rest for the year, he predicted.

The company aims to increase sales further by broadening Durex's appeal. "We want condoms to mean better sex, not just safe sex." said Mr Watts. SSL said its sex toy division was also performing well.

The company, based at Knutsford in Cheshire, saw pretax profits rise by 65 per cent to £17.3 million at the bottom line. This included lower interest payments as SSL reduced its debt levels.

Total sales increased to £222.5 million from £203.2 million, while the interim dividend was unchanged on last year at 2p.

Mr Watts said SSL had no immediate plans to sell any more of its over-the-counter brands following a string of disposals.
