You've already explained it to yourself. You're at the age where feet ache. That's just what happens.
But think about the days it doesn't happen. Barefoot around the house. Sandals in warm weather. The ache goes quiet — and it comes back the moment you put on "real shoes."
Here's what nobody points out: most footwear is built around a toe box narrower than the foot going into it.
Every hour you wear them, your toes are held together in a shape they were never meant to hold. The forefoot can't spread. The pressure has nowhere to go, so it concentrates — under the ball of the foot, along the outside edge, wherever the shoe is tightest.
The Aerion is built the opposite way. An anatomical wide toe box that lets your foot sit at its actual width. Nothing squeezing. Nothing forcing your foot into a shape.
Most people notice it in the first hour. Not because something was added. Because something was finally removed.
