And Toronto is cold for a lot of the year.

They've got to be warm, they've got to be waterproof,

but also, they've got to stop you going arse over apex

when you suddenly walk on a patch of ice.

and it's part of the Challenging Environment Assessment Laboratories

- If you want to find out whether people are at risk,

at risk of falling, at risk of a road accident,

at risk of something, you need to put them in a challenging environment

What we have is four modules for different things.

We have the world's most realistic driving simulator now.

When it rains in our simulator, it actually rains.

We also have StairLab, where we have people walk up and down stairs,

and we suddenly and unexpectedly move the room

and we can see how effective the handrails are, or the stair design.

21,000 people in Ontario every winter, on average, end up in

our emergency rooms because they fall on the ice and snow.

So the purpose of WinterLab is so that we can do two things.

One is that we can test the boots, and inform consumers what they should buy

and the other is we can help companies and ourselves develop better boots.

- I know I'm harnessed in, but that is terrifying!

We can generate winds, we can actually make nice, white, fluffy snow,

we can control the air temperature very precisely

and we can control the temperature of the ice very precisely.

We actually have a group of... graduate students(!)

like every other university lab you've ever been to,

because they're not very expensive and they're sort of disposable(!)

who do this testing and because we want some uniformity.

- It's a good harness, very good harness.

- Now, in order to test the performance of shoes,

we choose to put WinterLab on top of a platform that we can gradually tip.

- It does feel ever so slightly like gravity is shifting.

- We tip it as you walk up and down until the moment that you slip.

We have an angle which we think is just acceptable.

We actually take the minimum value of several people

if you can make seven degrees up and down comfortably,

- This is the good shoes, I can just, oh, okay, yeah.

- At the moment, we've got a scale of three snowflakes

and that was because the first time we ever did this,

90 out of 100 boots failed to get one snowflake

and nothing got better than one snowflake

so to publish it as a five-snowflake scale looked a bit depressing.

We've already tested some prototypes for next year

and they're getting two and three snowflakes.

- That's fine, I put my foot down and it just stays where it is.

- We are really quite confident that eventually

we're going to be able to add some more snowflakes at the four and five level.

It raises another interesting point, and that is:

We're a long way off that yet, but of course, more than half

the falls that you experience are people tripping up.

We will eventually decide whether a five-snowflake shoe is a good idea or not.

I'm really happy, in two years we've done two things.

One is that we've changed the buying habits of people

and the other is now the industry is improving the quality of boots

- Thank you very much to all the team at WinterLab

here at the Toronto Rehabilitation Institute.

I swear I'm not deliberately trying to do that.
