Leonardo da Vinci described the human foot as "a masterpiece of engineering and a work of art". And to make sure Clark's can look after it better than anyone else, they've studied it. From the cradle to old age. They've looked at the way it develops. They've scrutinized its bio-mechanics, the way it moves at work, rest and play. They've deliberated on what it takes to keep feet healthy and happy. And what they have learned is what helps them make the perfect shoes for you.
