Sockguy Myriad SGX SocksAt the top of Sockguy's elite sock hierarchy sits the Myriad SGX. They're made for athletes that demand the most with Sockguy's Elite Performance Formula, a blend of polypropylene, nylon, and spandex. The new SGX line offers a compression fit that feels great and provides optimal ventilation with a reduced friction profile. The heel and toe are reinforced, and the stretch to fit sizing prevents bunching.FeaturesCompression ribbing helps prevent fatigue by increasing airflowMesh upper maximizes ventilationSnug arch support hugs foot for maximum comfort and reduced slipFriction-free sole lets you go longer and pedal harderMaterial Elite Performance FormulaCut CrewCuff height 6"Size ChartSIZEUS MENSUS WOMENSEURSmall / Medium5 - 96 - 1037 - 42Large / Extra Large9 - 1310 - 1443 - 48
