You wear shoes almost all day, so it is important that your feet are enveloped by natural materials. Because wool allows your skin to breathe, your feet will stay warm in cold weather and dry in warm weather. Yes, you read that right: you can leave the insoles in your shoes even when it’s warm! But the best news, especially for men: they effectively absorb unpleasant odours and moisture. This is good to know when taking off your shoes after a long day… They also work great in sneakers. After training, simply pull them out and let them air dry.
