Better sizing starts at the ankle.
Vital Socks are everyday compression flight socks developed with input from an orthotist. Unlike sizing systems based on shoe size alone, our sizing guide uses ankle circumference to help customers select a more appropriate fit.
Designed for travel, long working days and prolonged sitting or standing, Vital Socks make everyday compression simple and accessible.
Vital Socks are intended for general consumer use and are not a substitute for prescribed medical compression or individual healthcare advice.
