Irregular is stamped on the bottom, but can't tell the difference

These were listed as closeouts, not irregulars so we were surprised to see an "Irregular" stamped on the sole of the sock. My husband couldn't tell what the irregularity was in size or color, so we ended up keeping them. Haven't tested them in the snow yet, but based on our past experience with smartwool, I'm sure they'll be great.
