Is your relationship with your girlfriend not going well? Then try stepping into her shoes. Ten men ran in high heels with their girlfriends yesterday in Hong Kong's first high heels running competition, as part of celebrations to mark the 100th International Women's Day today. The idea was to enlighten men on one often painful aspect of women's lives. The message got through. Bobo Ng and Kenny Cheung, the winning couple, wore matching white T-shirts with a footprint design. 'I wanted him to feel what it is like to wear heels, but he still runs faster than I do,' Ng said. Cheung said: 'My girlfriend looks good in heels, but now that I know how painful it is, I won't ask her to wear them.' Michelle Lee and Frederick Chan dressed as an Indian prince and princess for the race. Chan said running in high heels was painful. Lee had fun but wasn't keen to see her boyfriend in heels again. His hairy legs weren't quite the right look, she laughed. Allen Cheung, who is 1.8 metres tall, felt 'the extra elevation provided an interesting view' but could now appreciate what women had to put up with. His girlfriend May Lai helped him shop for the shoes and opted for a pair of open-toe platform shoes because his feet were so big. Cheung said the saleswoman gave him a funny look, and he felt pressured trying on women's shoes as many people were staring at him. Champion of the individual race Holly Yan sprinted the 25-metre track in five seconds while wearing a pair of two-inch high heels, the minimum height set by the organiser. She had heard of similar competitions in the Netherlands and was pleased Hong Kong finally had its own race. Fun aside, 10 unions rallied separately for women's rights yesterday on the eve of Women's Day. Most called for support for unemployed women, babysitting services for working mothers and equal pay. The Hong Kong Federation of Trade Unions quoted government statistics last year that showed non-skilled female workers earned HK$5,500 a month, HK$1,500 less than their male counterparts. A Hong Kong Confederation of Trade Unions survey showed that the problem was especially serious in catering, import-export and manufacturing sectors. In Chinese restaurants, waitresses earn 57 per cent less than waiters, whereas female cooks in fast-food shops earned 55.2 per cent less. Both unions urged the government to increase support to grassroots women seeking jobs, and enact laws against age discrimination. The Caritas Community Development Service urged the government to offer free and regular gynaecological check-ups, as its survey found that 30 per cent of 432 women polled had never had such checkups.
