When we talk about running socks, "comfort" is the number one criteria. If a sock doesn't feel right, it’s going to end up buried in the back of your sock drawer after one use. But there’s a massive difference between "cozy" comfort and "performance" comfort.

We recently received a great question from a customer planning a high-altitude expedition. He’s heading up to 6,400m and was looking for advice on how to avoid foot issues during the long trek, as well as how to manage his gear for that final summit push.

The Ferrari Effect

Think of the difference between running in heavy hiking boots versus lightweight racers. When you strip away the excess, you feel faster. It’s the same psychological and physiological "Ferrari Effect" you get when you finish a period of resistance training (like rucking with a heavy pack) and finally drop the weight. You feel light, springy, and agile.
