Slick Willie’s Is Among The UK’S Leading Skate Retailers, With One Of The Longest-Established Skate Shops In London. Here at Slick Willie’s we’ve been supplying skate gear since skateboarding was kicking off in the 1970’s, making us London’s oldest skate store. Our humble beginnings saw us open our shop in the heart of the city, right by inline skater’s London paradise, Hyde Park, where you can still find us today.
