I've bought these super socks three times already. They last about a year of constant use. The latest batches seem to stretch faster. But overall, these are comfortable socks that don't make your feet sweat. They're moderately warm. I wear them in winter, spring, and autumn. Some people write that they run small, but that doesn't seem to be the case. I wear size 43 and they fit perfectly. The main thing is to wash them properly and not dry them on high heat (otherwise the elastic stretches). In one photo, there's an old sock; for some reason, the new ones are lighter.
