Yes. Thanks to the natural base properties of Merino wool, our shoes are breathable, temperature-regulating, moisture-regulating and antibacterial. You can wear our Merino shoes barefoot, and your feet will neither sweat nor produce any unpleasant odors.When you first purchase your Merino shoes, we recommend that you wear them with socks for three days. This will help you avoid potential blisters while allowing the shoe to mold to your foot.
