The breathability of the sole of the shoe is guaranteed by openings in the tread sole. Water vapor from sweat is directed towards these openings. But if you step in a puddle? You’re still protected. The GORE-TEX membrane surrounds your foot. So while sweat vapor molecules can escape, water can’t get in.

This construction features openings positioned at the side of the sole. The breathability of the sole is guaranteed by a grid that directs water vapor from sweat via openings to both sides of the shoe. But if you step in a puddle? You’re still protected. The GORE-TEX membrane surrounds your foot. So while sweat vapor molecules can escape, water can’t get in.

This construction allows moisture and heat to escape from below the foot through the GORE-TEX material into the open structure of a spacer and then out of the shoe through the side ventilation outlets.
