Review on RTZAT Merino Wool Hiking Socks - Thermal, Moisture Wicking & Cushioned For Outdoor Activities by Dan Germain

I have no need to keep my feet warm but they ironically do keep my feet cool in hot weather. It's said that sandals are best for the heat but thick socks in hiking boots actually feels cooler, perhaps because the socks breathe and the feet have no sun and sweat. My feet do sweat a little but the socks generally feel dry when I take them off after a full day walking in the park on a summer day. Thick socks are what make hiking boots great, as you can walk for miles like its nothing compared to thin socks. So the comfort of these socks is definitely real. I would describe them more as insulating than thermal.
