IMHO, it’s the shoe and not the sock that should be the main focus, and that the brand of shoe doesn’t really matter. Fit matters. So does material. Shoes with good padding at the sole, and that overall fit a little loose at the beginning of the day are the answer for me, as all feet naturally swell during walking / as the day goes on. (If the shoe “fits like a glove” at the beginning of the day, it’ll probably be too tight as the day wears on.)
Friction, heat, moisture: that’s the combination that causes blisters. Loose enough, well-ventilated shoes eliminate the first two.
For me, plain, 100% cotton crew socks work great. Depending on where the blister(s) form (e.g., heel versus top of toe) would help guide if a full length sock is needed, or if a no-show would work. I’ve never used wicking socks other than for winter sports, and even then often wool, so my experience with synthetic socks is limited. Synthetic blends or full synthetic in “regular” socks do not work well at all for me, as they cause my feet to sweat and they retain the moisture.
Unless walking 100 yards or less from the room to the pool, I would avoid flip flops like the plague.
Anecdotally, an above-poster put a picture of some ugly (to me) sketchers walking shoes. I bought a pair of those and brought them, never worn (so not broken in) as an emergency back-up on our most recent trip. I wore them the overwhelming majority of the trip and they were amazing. They got a little wet on Tiana’s and dried pretty quickly. Speaking of - again, moisture contributes to blisters. I’d recommend carrying a dry pair of socks to change into, in case feet get wet on Kali River, a downpour, etc…
