I think I have a part of myself which is a woman. When girls are together, they speak completely differently than when there is a guy around. But, with me, they don't see this masculine thing stopping them, and there is not this boundary.

Funnily enough, the most difficult style to do is the plain pump because it needs to look good on a variety of feet. I compare it to having a good bone structure. Make-up will make you look good, but it helps if you have a good skeleton to begin with.

There are few plants that are ugly. It's how you use them that may not be pretty.

Designing my shoes, I'm thinking timeless. Not trendy.

A lot of women don't like when they're sort of fat, but a fat foot is as beautiful as a skinny foot. Think of Greek statues. Look how many people love the foot of the baby! There is something super-charming about the baby foot.

The highest heels I do are six-inch heels - but mostly only dancers can wear them, since they are used to being on point in ballet shoes. Their feet are arched.

For women raised in the '70s, high heels can still carry a stigma; they're associated with being stupid, with just wanting to please a man. Other women find them empowering.
