A study by Otago University has proven that the practice of wearing socks over shoes actually works.
Researchers at the university department of preventative and social medicine intercepted pedestrians on Dunedin streets one icy morning last winter, recruiting them into the study.
They were either left to go on their way, or given a pair of thick wool, acrylic blend socks to don over their shoes.
Dr Lianne Parkin who headed the research, told Morning Report those wearing socks over their shoes, found the footpath significantly less slippery than those with just shoes on.
She said they showed greater confidence and were less likely to crawl or cling to parked cars.
