With a ridiculous heel pocket and lightweight/thin profiling, these quickly became my socks of choice over Icebreaker (I know, I'm sorry), Smartwool (sorry again) and even some snowboard brands like Volcom and eesa which were more stretchy but less comfortable over time. Merino wool is great but spandex and polypro will only enhance the socks performance and ability to retain it shape without over powering the Merino's mysterious magic. It's called a ski sock, but I snowboard in them, I know Fox River makes a snowboard sock but the heel and ankle detail on these just make it a good sock no matter what you're up to. There are no awkward seems to get in your way and they're sized appropriately which is a first for me in any sock- buy according to the size chart. Get some!
