I just finished the muddiest race of my life yesterday. 3 hours of mud, water puddles, and rain.
Generally, I never go for merino socks when I run. Most socks claim breathability and warmth but fail to deliver on either while bunching and creating hot spots. These socks are the first socks that actually deliver on what a merino run sock should be. Breathable, warm even when it's 45º and raining, and no hot spots, even in the worst conditions. I might be a merino convert now (but only for my couriers).
Wonderful

Amazing thing about these socks are that even when they sweat, they don't smell and that's beautiful when using it for reruns. When washed, these socks still keep themselves intact and the feeling is oh so amazing.
Love these socks. I admit to wearing merino socks for days without swapping. In the first week of owning my new Courier merino socks I've worn them for runs, walks and all day at the desk without switching them out. Give 'em a shake and put 'em back on. They fit great, don't retain odour and are comfy. Definitely won't be my last pair.
