VeloToze Aero Extra Tall Socks, for cyclists who are tireless in their quest to save every fraction of a second, the role of aerodynamics is fundamental. This is why VeloToze designed the Extra Tall Aero Socks - XT to become your ultimate secret weapon. Extending 2 inches (5 cm) more than the standard Aero Socks, these socks are the key to unlocking unparalleled aerodynamic advantages. Unleash extra speed: just like our standard Aero Socks, the Extra Tall version offers extraordinary aerodynamic benefits. With their extended height design, you receive an additional boost of advanced aerodynamic fabric for extra performance advantage. UCI approval for tall cyclists: the VeloToze Extra Tall aerodynamic socks still comply with UCI regulations for most cyclists taller than 5'10" (178 cm) or with longer limbs. To ensure you meet UCI regulations on sock height while maximizing your aerodynamic advantage, measure the distance from the head of the fibula to the lateral malleolus, then divide the length by 2 to determine the maximum legal UCI sock height. If your measurement exceeds the following specifications, these socks comply with UCI regulations for you. S/M: sock length at calf is 23 cm/9.1 inches L/XL: sock length at calf is 24 cm/9.4 inches
