Swiftwick Vibe Zero Socks have a plush feel underfoot without bulk thanks to a half-height terry loop footbed and a very mild compression fit that improves circulation through the foot. Olefin fibers mange moisture with anti- microbial protection as the seamless toe works to prevent irritation; a slightly relaxed arch and y-heel contour keep them right in-place no matter how serious the pace gets.
