I would like to offer a different perspective-
We have had cotton marketed to us as the "natural" choice for 100 odd years. And while it is natural - you should NOT wear next to your skin in hot weather. Why??? For the same reason cotton makes the best thick bath towels....it HOLDS MOISTURE !!! Holding moisture, along with he bacteria that is part of us and the perspiration we excrete can create skin issues - and even if it does not...IT KEEPS YOU HOT!
So - for comfort and safety, try to consider proper orthotics ( Urthotics.com ) with high smartwool content socks ( AND...compression socks that are knee highs are best!) in good quality hiking boots. Yes I said boots. You will benefit from being able to lace them to fit YOUR foot. Here is a link that gives you 6 options for lacing to accommodate your feet and gain support that benefits your feet, knees, hips, and back.

Our feet are our foundation. And that foundation affects and supports all the structure above it. Yet, good and proper footcare is one of those things many of us take for granted.
I agree that you should be comfortable. And I also understand that some of what I am posting herein seems counterintuitive if not downright controversial. So let me qualify WHY I am an avid ( READ: RIBID
) proselytizer about this subject:
Left heel was taken off by shrapnel and surgically put back together as best as possible. All tendons to the toes on my left foot were severed and fixed as best as possible. Still have shrapnel above the inside of my left ankle. I have had more than 1/2 of the major bones in my body broken at least once. I have had 5 major knee rehabilitation surgeries including bone an tendon grafts. A twice broken back. destroyed and rebuilt shoulder. Herniated disks in back and neck. And a permanent crease in my skull and 40 plus stitches to accompany it. Want to test a shoe for support and comfort? Or a sock? I am your guinea pig.
What I am saying is - I have spent a tremendous amount of money to find ways to be able to stand long term and not be in agony. And surprisingly......the kinds of shoes that we usually think are comfortable to our feet.....are usually not comfortable to the rest of the body for standing extended periods of time.
Find an Orthotist to measure your feet and loot at their condition. Consider your other health issues including weight. Shoes - AND socks......are a LOT more important now, in our older years. Sure, we could get away with a lot when young and bulletproof . But those #$%^& bullets - or just time change your foot needs -and THAT affects your back, knee, and hips needs..
I hope everyone takes a pause to consider this - and I wish you to be pain free.
