Shoe manufacturer and leading Timberland and Skechers supplier, Kingmaker Footwear Holdings Ltd, has posted a 25.5 per cent slide in full-year net profit to HK$111 million from HK$148.8m in the year-ago period. The firm said rising leather prices, retail discounting and lower productivity at a new Vietnamese plant were behind the plunge, while turnover was flat at HK$1.04 billion.
