Bringing together the technologies of our highest performing sock models the brand new Aero Sock takes multisport performance to a whole new level with air-defying speed. Tested & optimised in the wind tunnel the front fabric features structured lines to increase boundary layer (surface) turbulation & save over a minute over a 180km Ironman bike ride. Our brand new Aero.dots build a line from the malleolus to the seam directing the airflow to reduce turbulence at the rear of the sock decrease drag & save a few more watts. The foot structure follows the design of the Ultralight running sock with featherweight sweat-wicking mesh for optimal ventilation & thermoregulation in hot conditions. The reviewed wider toe box brings more comfort & enhanced proprioception to your run while a special knit around the heel offers gentle support as the pace ramps up. A light arch support prevents the fabric from twisting & irritating with extra terry padding over the big toe to save you from blackened nails & bruising. Underfoot a clever pattern of 50% 3D. Dots & 50% Flat. Dots cushions impact & adds grip in the shoe. It also provides gentle micro stimulation to increase venous return & delay fatigue while Ventilation is also enhanced as air circulates between the dots. At the rear of the sock ultralight mesh takes care of thermoregulation without adding weight & a full Achilles stripe in dot technology offers reassuring support in all disciplines. The cut is higher than our trail & running models for optimal aerodynamic performance whilst remaining within UCI limits. Silicone inserts around the seam prevent the material from sliding down as you switch from the bike to the run. The fastest sock in the bunch the revolutionary Aero Sock is set to be your new footwear of choice from your local tri to the lava fields of Kona. KEY BENEFITS Proven aerodynamic performance with structured material & Aero.dot technology to reduce drag & increase speed Maximum thermoregulation & ventilation thanks to featherweight mesh panels helping keep your feet fresh & cool Ultralight fabric around the foot & calf for high-performance ventilation & comfort when racing in hot conditions
