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.
That’ll outlive the small ones as well. I usually just buy the same amount of large and small socks and usually at least 2 pair of each, so I end p up with 4+ of the same sets. They’ll dwindle down to 1 pair in the end. One ship is even so nice to put the size in the socks, 39-42 in yellow and 43-46 in blue. (there is even a cheap shop that does the same, but those sock don’t match, 39-42 with horizondal lines and 43-46 with vertical lines… why would those need sizes in them ;) )
