The SYMPATEX Moisture-Tech lining is covered by the warranty of SYMPATEX TECHNOLOGIES GmbH Unterfohring (D) – www.sympatex.com – info@sympatex. com, which has a “customer service” office in every country.
ANDREW recommends choosing the type and size of the shoe carefully, so that the foot is snug and secure. This will not allow the foot to move too much inside the shoe, preserving the STYMPATEX lining and maintaining its characteristics over time.
During and after use, it is good practice to ALWAYS remove (also by extracting the insole) any sediments or pointy objects (soil, sand, small stones, twigs, thorns, etc.) lodged inside the shoe that, with movement or pressure of the foot can irreparably damage the SYMPATEX membrane.
