Great idea.

I'm going to offer you a piece of advice here though because I'm a "never look for a pair of socks" man and I also love good socks.

Years and years ago someone bought me a pair of Nike dri-fit socks. Put them on. Like having your feet caressed by an angel.

This is great says me. Then every time my wife or kids asked me what I wanted for my birthday or Christmas.... You guessed it ... Black Nike dri-fit socks. This went on until they complained that they wanted to get me something other than socks hahaha.

Now I open the sock drawer and pick any two and instant pair. Magic. No pairing required because honestly who has time for that.

So yeah great idea. I'd just suggest being careful and getting some up front so you know they're not sweaty or whatever. The elastic around your arch is the good stuff.

Edit: I did think of something else the other day and meant to reply then when I went to I'd forgotten but it'll come to me.

One thing I did buy 10 of before was HDMI cables but I was in a market in China at the time and before COVID. Think I paid about 2 euro each because myself and my mate got ten each and they did a deal.

I'm sure they're cheap in bulk online now though. No regrets there but my requirements might not be the same as yours.
