London shoemakers T&F Slack are known for their whimsical, and sometimes unorthodox approach to footwear. T&F continue those traditions through their Spring/Summer 2012 collection, as the label introduces their classic Nubuck Derby Shoe in the vibrant and energetic Turquesa colorway. This traditional five-hole piece is crafted from nubuck leather in T&F’s Notting Hill factory in London. Its upper is offset with a contrasting tan welt, stacked atop T&F’s lightweight micro-sole in a deep shade of royal blue. Matching waxed blue laces round out the youthful package. It takes a certain level of gumption to wear a turquoise Derby, but if you’re up for it, you can snag your own pair of this unique shoe at oki-ni. They’ll set you back £175 GBP (approximately $185 USD).
