Mar 20, 2017 4.0s HAVE (FINALLY) ARRIVED!! THEY WILL BE AVAILABLE WITHIN 24 hours!! Yes, you heard right! After going through countless samples from close to a dozen manufacturers, testing for design, fit, comfort, function, materials, etc., we've finally landed on our latest (and GREATEST) version of Ninja Sox....the 4.0s! It has truly been a long and arduous journey, but I think the wait was well worth it. While we could have just gone with the same cookie-cutter no show socks everyone else is churning out, we made sure that each stitch, thread count, sizing, stretchability, was well thought out and catered to the our no show sock customers. We're absolutely elated to be able to share our latest version with the rest of you. We appreciate your support and understanding as we took some time to perfect the no show socks that we call the Version 4.0s!
