Twelve recreational football players (mean age 20.3±1.1 years) completed a 26 m dynamic agility course at their maximum running speed. 3D kinematic and kinetic data were collected for three maximum speed 45° side-cuts, and 180° turns in two different sock conditions. Comparisons were made between a sock with a high static coefficient of friction (GripSock) and a regular sock (CompressionS). The Gripsock condition significantly increased utilised traction (COFu) and a reduction of GRF angle (GRFα) were identified during the braking phase of the side cut (COFu: + 9.3±10 %; GRFα: - 3.1±2.9 %) but not in the side-cut propulsion, turn braking and turn propulsion phases. Speed perception was raised in the GripSock condition (+ 18±30 %). However, wearing a sock with high frictional properties did not significantly reduce in-shoe foot sliding in any examined direction nor did it significantly reduce running times over a functional traction course. Evidently, the relationship between in-shoe traction and running performance is complex and likely dependent on the overall interaction of shoe properties and the type of athletic sock.CC0 1.0 Universalhttps://creativecommons.org/licenses/by-nc-nd/4.0/FootwearTractionPerformanceSlidingPerceptionArticle1942-4299Footwear Science
