Seems like a good hack for shoes too (admittedly, just the toes section). This might come in handy as we in Ireland are about to experience some severe snow/ice storms over the next week and are perpetually unprepared for the snow which briefly hits each year. I'll be trying out the shoe-variant at the weekend!
PHYSICS PRIZE: Lianne Parkin, Sheila Williams, and Patricia Priest of the University of Otago, New Zealand, for demonstrating that, on icy footpaths in wintertime, people slip and fall less often if they wear socks on the outside of their shoes.
