supernothingOn their web page http://darntough.com/men/mens-hike-trek/light-hiker-micro-crew-light-cushion, click the pullout on the left of the page for a description of height and cushioning.
Looks like micro-crew goes mid-calf, so above a typical boot, and "Light Cushion: Light and strong with "just enough" cushioning. True Seamless™ construction and 17.5 micron wool create a smooth ride. Mmm mmm good!"
supernothingI've bought a couple pair of their running and regular socks, they're awesome!!! I can only imagine these are the same, I might grab a pair.
