So what are "Sock Rockets"? Imagine taking the addi Turbo Lace needles with the extra-pointy tips in a fixed circular, then adding the shiny nickel coating that gives the classic addi Turbo its incomparable zip. The result is the Sock Rocket! The Sock Rockets are available in two cable sizes - the 24" cable will work wonderfully in pairs and the 40" cable is perfect for the Magic Loop method (watch Michelle Hunter's video lesson on the Magic Loop if you haven't tried it yet). The needle sizes are US 0 (2mm), 2.25mm, US 1 (2.5mm), 2.75mm and US 2 (3mm).
