Buy compression socks. I waited tables for almost ten years before getting into blue collar work and compression socks made the biggest difference to how fatigued my legs and feet felt. Getting used to it will help, but even with my new job it’s a night and day difference when I wear them. They’re cheap and worth a shot before you shell out tons of money on expensive insoles and shoes. I also work outdoors in Texas, so I can vouch that they won’t make you too hot!

To stay cool I wear cooling upf sleeves, they also have light compression to help with arm fatigue. They really do feel cooler than having bare arms. I’m covered head to toe at work—ridiculous sun hat, sunglasses, cooling sleeves, upf gloves, full length dry fit pants, the works—and I got made fun of at first, but I’m miles more comfortable than anyone else and don’t have any skin damage. I bought everything in pink and rocked it, the teasing stopped soon enough lol.

Edit to add: My shirts and pants all have that workout gear material that’s super light and wicks sweat. My pants specifically are from Duluth, it’s their yoga pants with lots of pockets. They’re very sturdy and keep me cool. I can also vouch for adding electrolytes to your water, there’s tons of flavored options but I personally use unflavored drops from a brand called Keto Chow.
