These are my first coolmax ones from them. They are comfortable, well-cushioned and they last practically forever. They have just the right amount of cushion without being bulky.

They support my feet well without being too constricting. They actually stay up and don't get all bunched up in my hiking boots. Kept my feet dry, cool & comfy on a multi-day trip of daytime walking.

The padding is perfect for maximum comfort but not too much that your shoe doesn't fit. They are thinner on the ankle to be cooler, but still good and think on the foot for comfortability.

I imagine it'd only be worse if i wear them with hiking boots.
