Recent research by the University of Otago has discovered that wearing socks on the outside of your shoes will reduce the incidence of slipping over in snow and ice.

Bear Grylls demonstrated this on an episode of Man vs Wild a month or two back. The episode of the Bear in Patagonia climbing on a glacier was no doubt filmed sometime ago, like last year?

Why didn’t Otago University save themselves some money and just ask Bear?
