Really love these socks! They’re light, durable, comfy and breathable. I love both Stride and 400 models. I even wear the 1.0 collection around the house just because they’re comfortable.
These are the perfect crew height. I loved Collection 001, but for a plain white sock to run in they are great. They also stay white and I routinely lift weights in them. Bravo!
