That thing where you put on a fresh pair of socks and one has a hole so you think well I went to all that trouble to pull it on, this will be your last day little buddy, I’ll just throw it away after I wear it today.
Last chance underwear happen now and again as well but I guess it depends on where the hole is.
I do about the same, but I have 2 huge differently sized feet (birth defect) 1 foot is 4 eu sizes smaller then the other. I usually buy 2 pairs size 39-42 and 2 43-46, so I have 4 pairs of 1 small and 1 large sock.
Alas, the large socks are usually the ones that develop holes 1st.
If it’s so consistent, I’d just buy an extra pair of the large ones.
