Solid processed and pleasantly thin

The aluminum layer is incorporated between two other layers, so that cracking or flaking of the aluminum foil - as I have experienced in competitively priced models at the discount - is not given. Thus, the insole provides a long time good services.

The sole is thin and warm. Especially the thin processing leaves the sole in each of my shoes fit without the foot sits close in the shoe. The sole is in my opinion very good for leather shoes and sneakers suitable for ambient temperatures above freezing.
