Running is a huge category for us. To be able to run to work and have lightweight, breathable, windproof materials you can chuck in your bag that work on technical level but also on a lifestyle level are really important to me. I work out - and I think most people do - and I want to encourage women and inspire them in a way that fits in with their lifestyle.

My mum taught me to have a soul.

I get a real kick out of it, seeing people wear my designs.

The really great thing about my shoe store is that there's not one dead animal in it.

I think the moment that I'm very proud of is building a business without using animals. And, hopefully, changing people's perception of how you can do luxury fashion.

It's not realistic to live in the country at this stage. I've got a business in London. I beat myself up about it all the time.

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.
