The consumption of animals - whether you're wearing them or eating them - is extraordinarily damaging to the planet. There are over a billion animals killed a year for food, half of which don't even get eaten. And there's over 50 million animals killed just for fashion.

I run a lot. If I don't have time to go to the gym or don't have time to work out properly, I will go for a quick run. I think running is a great way to stay fit, and I really concentrate on fitting into a realistic urban lifestyle.

Someone from Manolo Blahnik went into my shop and said: 'These shoes are not vegetarian.' That's the highest compliment, because you just can't tell that they are, and they are. My mum taught me to have a soul.

We try to make earth-friendly decisions whenever we can, as it's part of our brand DNA.

I was first drawn to active wear because I enjoy working out, and it's very important in this day in age. I really felt women were getting the tail end of the design in active wear; not getting the technology or design we deserved. It was reserved for men. We were getting the leftover work from the sports design houses.

The really great thing about my shop is that there's not one dead animal in it. ... Manolo's got a load of fabric shoes as well! We use plastic, fabric, rubber- anything but leather. I almost feel like I've been put here to show everyone that it's unnecessary.

I didn't want to be thirtysomething and not know what I was going to do. I was quite afraid of that, there were quite a lot of aimless kids around, in that 'other' side of my life, who didn't really know what to do because they always had a bank balance to fall back on and they were quite lost.
