Couple the sock with a dynamic, low profile, single layer Aeroswift cuff and the Levitator Lite is an instant choice of top professional cyclists for the finest, best fitting, performance sock they could own. A perennial favorite that's often spotted amongst the circuit. Thin, light and wicked fast sums up Levitator Lite.
