These pores are approximately 20,000 times smaller than a drop of water but 700 times bigger than a molecule of moisture vapor. So, whilst water droplets cannot penetrate the GORE -TEX membrane, moisture vapor, namely perspiration in gas form, can easily escape.- GORE-TEX® has developed 3 specific types of membrane for the footwear sector, each with specific functional properties.Vibram:- Vibram is synonymous with the sole for mountain footwear, an essential component for the safety and technical performance of the product. Vibram's experience is condensed in the research and development of specific compounds for use on different terrains and environmental conditions, AKU's contribution is based on the design of the tread profile, conceived and designed according to the intended use of the product. From this synergy are born soles that AKU adopts on many of its models, generating its own exclusive standard of performance.
