Good cut

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size
  • Size Bought: M

Most of Smart wool sock cut is either to low like the mini one or very high crew socks. This is more like normal 3-4 seasons cut, high enough to cover my base layer bottom and not too high and not too warm like crew socks only made for winter. This is more natural cut socks. I like it.
