These socks are a bit thinner than I was expecting but they feel good and keep my feet warm enough. I would rather use heavier shoe covers and lighter socks to keep circulation going to my feet anyway so I'm enjoying them. I wouldn't really recommend using these below 35 degrees but they're excellent for the 40-50 range with the right shoe covers for sure, and of course Merino wool is IMO the best material for socks (and base layers, and headwear, etc.).
I bought these socks because they're yellow and make more visible to drivers, I hope. Also because they're wool and warm. I layer them with wool no show socks below which seems to be good for me to about 40 degrees.
Long time fan of merino wool products but some wool socks can be too thickwarm. These socks are prefect for all types of weather even hot days and have worn them for road, cyclocross and even a DH run. They're well built, fit snugly but not too tight and seem to be wearing well. Only minor complaint is the vibrant color it difficult to get clean after getting muddy so get a black pair for those days.
These socks are made of lightweight merino wool, which insulates well in all conditions and won't crowd out space in tight fitting shoes. I've worn these on several hot long rides, and my feet never felt clammy. The high cuff provides good heel support-snug but not too tight. For reference, I wear size 42.5-43 shoes and the medium size socks fit perfectly.
I can only really judge socks by whether I want to put them on when Im going out out for a ride, and for these, I do.
They are medium thickness but still good in warm weather.
These have quickly become my go-to socks. So comfortable in all kinds of weather, not bulky at all. Not itchy, either. I have size 11 feet, and these guys fit a bit small, just perfect for me. Nice compression without pinching at the top.
