Comfortable insole that cradles the foot. I wear it in a hiking boot. Lightweight step that relaxes and doesn't hit you. The size has no discrepancies, so you choose whatever number you wear in the shoe. It is durable material and hasn't "deflated" after 4 months of daily use, even in summer. Finally, you can't call it cool as it has an issue with ventilation. However, it has satisfied me, and I have already bought a second pair.

I have had them for 1.5 months now in work shoes that I wear for over 8 hours a day every day and they are excellent.

In the one month that I have had them in sports shoes, they are great. Comfortable, the foot does not sweat excessively, and they still seem to hold up.
