Spoiler: it's not just about fatigue
If you've run a marathon, stood for hours without squatting, or carried heavy bags - there are no questions asked. But if nothing like that happened, and your feet feel like they're not your own by the end of the day - this could be a direct consequence of... Yes, yes, improperly chosen shoes (you guessed it, right?)
The foot is immobilized
When shoes squeeze the toes and restrict movement, the foot feels like it's in a cast. But it has muscles, ligaments, 33 joints, and it's critical for each of them to move.
Fact:
When walking in flexible shoes or barefoot, the activity of the small muscles of the foot, which help keep blood circulation in good shape, increases 2 times.
The "pump" does not work
The foot is not just a support, but a part of our circulatory system. Each step = pressing on the pump: the muscles contract and push the blood up.
When the shoes are hard, the sole is thick, the foot does not bend - the pump breaks. The blood gets stuck at the bottom. Because of this, there can be a "buzzing", and pain, and swelling of the legs.
The load goes where it should
If the heel or toe is raised in the shoe, the weight is distributed unevenly. Somewhere the muscles are overloaded, somewhere, on the contrary, they do not get enough load. The result is muscle spasm.
And
in tight shoes, the feet often overheat. This interferes with normal lymph drainage, the foot swells. By the evening it feels like you were carrying bricks. Especially in the summer
So,.. what to do about this?

Move your feet more often during the day.

Don't sit or stand in one position for hours.

Take off the "armor" from your feet. Let them breathe, move, feel.
Let the shoes help the foot work, and not do everything for it and "break" it in the process.
So if you don't want your feet to "buzz" in the evening, perhaps you should start not with ointments and baths. But with
what we wear during the day. Although baths and other pleasant things for the feet are also wonderful
