Unbelievable soles.
In Meindl Bundeswehr boots, they fit like a glove.
The cushioning is very soft, resulting in the hardness of the boots being diminished.
They are excellent for mountain hikes.
I highly recommend them.
Just be careful with the height inside the boot, as the soles are quite thick and in my test, for example, with Lowa Zephyr, the foot hits the top part and it is uncomfortable.
