I buy them in bulk from a factory outlet nearby, so the price is reasonable given my income. Furthermore I find they can withstand the hilly and muddy half marathons that I run, while keeping my feet in good condition. I like to run after work, so by wearing these socks to work I can give myself one less thing to pack/change into. (I dislike the aesthetics of dark socks with shorts)
As I must wear smart clothes to work, and white socks with a suit is a fashion faux pas, this means I must wear smart boots to work. But this works for me as then I choose zip-up boots to save time doing laces.
I acknowledge this 'life hack' is a minor time and convenience saving with some drawbacks, and clearly won't work for everyone. But as a working father with two young children, this gives me a little more time to spend on myself, and a little more time with them.
