DeFeet’s EVO Jet™ sock has undergone extensive wind tunnel testing and results have concluded that the product demonstrates market leading aerodynamics. Test results showed that at 38mph the Evo Jet saves a cyclist 24 watts over shaved, bare legs without socks. Bare legs test results are shown to be more efficient than typical, flat knit non-aero fabric cycling socks. Exactly why socks are so critical in aerodynamics is because they have exposed, front-facing drag surfaces that rotate directly into the wind with significant turbulence in the area. Wind tunnel testing of the EVO Jet took place at the A2 Wind Tunnel in Charlotte, NC, and was conducted under the watchful eye of renowned cycling aerodynamicist Heath Dotson. Evo Jet was tested using a human rider with yaw angles.
