You can get by without swearing socks if you wear your shoes for a short time and then air them out. Nothing has a chance to make a fungal or other problem since the shoes are dry and resting. You can see this with climbing shoes- you are not supposed to wear socks with them for the best traction, you work out in them for an hour, and then the next time you get them out they are good as new.
I have gradually phased out the annoying little half socks I used to have to wear to get a full workday's wear out of my dress shoes. All my socks are handknit or otherwise wool. And there are no, no show socks remaining. No problem except now I love these platform sneakers and wear them every time I leave the house.
I am a lofty, alpine, almost airborne 5' 5" everywhere I go, now. And although it is deep winter in northern California I can feel my feet sweating on hikes and similar. So, time for a hand knit pair of no show socks. I read online that these shoes break in to a larger size- and these have- so a nice bulky pair of socks will be ideal. That also means that these hand knit socks won't go with my other shoes since those fit me properly.
And that means I can dye these socks to match the shoes and hopefully achieve a no show effect even with a little dyed-to-match sock showing and thus circumvent the irritating issue of reaching into a sweaty shoe to grab a little twist of sock and smooth it back over my heel.
Knitting these two-at-a-time because otherwise all bets are off as to when I'll have the urge to cast on and complete a second sock- as a bonus, you can change anything you want on the fly and not worry to much about making a note since both socks already have the change.
I straight up can't start two pairs of socks on two circulars, only tried once but it was very uneccessary. Since I have double pointed needles I just cast on and knit each toe then transfer to circulars. If I only had access to circulars I think I would do the same thing, cast on one then set it aside, cast on the other, then put both on the circulars to work. I strongly recommend using two different circulars. Then you just knit every stitch from one type of needle, then drop that needle and work every stitch on the other type. So here I am knitting nickel to nickel.

Now I knit bamboo-to-bamboo. I would like if this needle was a little nicer so I may pick up a wooden size 3 to replace it.
Because I'm knitting two at a time this is going very slowly. Every round is 120 stitches or so. I'm just about done though since after I make a spot for the heel and work a little 2x2 ribbing it will be time to cast off.
