Yes! Hidey Socks are truly antibacterial because of the specialized fibers we used to design this sock. Let's see what our customers have said:"The first time I tried hidey socks, I intentionally left them on for three days in a row. To my surprise, my feet didn't stink at all! They were breatheable, sometimes leaving my toes a bit cold, but overall extremely comfortable. - David Aparicio "" After 6 hours in these Hidey socks, no odor!! - Vilma Villalobos "" My girlfriend bought me hidey ankle socks and I was sorta skeptical about them so I put them to the test and after 2 days they really didn't smell! - Justin Delagarza "
