Here at Browns, we like to think we know a lot about architecture. Shoe structures, that is. That's why we've fallen (you guessed it) head over heels for Nicholas Kirkwood's sculptural heels. Launched in 2005, the avant-garde footwear label has gained traction for its boldly graphic and futuristic collections. Kirkwood often uses contrasting influences to shape his designs, such as nature and machine, tradition and technology, and a dichotomy of feminine and masculine forms. Suits us - we were never a fan of commitment, anyway.
