I just saw this BBC news clip Does Canada have the solution to slipping on ice? at about 1:20 into the clip (not counting the commercial) a scientist says "most footwear performs poorly" he also says just looking at the tread of the shoe/boot is not a good guide.
For those who can't watch the video. Canada has an indoor lab with ice floors that can be angled to test traction on both frozen and partially melted ice. There is a related web page that has ratings for different boots. Neither the news clip nor the web page tells me how to identify good footwear, there is an option to see ratings for tested boots.
We have a couple of existing questions about footwear and ice, that mostly talk about how to walk, or what & when to use add on traction devices.
- What's the best way to avoid slipping on ice?
- Is it worth getting snow shoe chains/spikes for only a one week trip to a snowy area?
- Are Ice grips worth buying?
Choosing boots is complex, and the top rated boot might not fit my foot or maybe it is not available in my area or...
If I am in the boot store without a rating source for boots, how can I identify which boots will have the best soles for walking on snow and ice (and be safe on hard floors indoors)?
