Tradition Many years shoes with GORE-TEX® provide high inner comfort in any weather and in any conditions. The main factors affecting this comfort is breathability and waterproofing. These features provides a unique GORE-TEX® membrane. Microscopic pores in the membrane are impervious to rain and moisture from the outside, but remain open to the leakage of sweat and excess heat. Your feet are always dry and remain in comfortable stand. Gore-Tex® Extended Comfort Footwear with Gore-Tex® membrane is the choice from the moderately warm to hot conditions or during intensive use between internal and external conditions. GORE-TEX® membrane without thermal insulation layer provides a minimum level of accumulation of heat in hot weather and also at high physical strain. To achieve this level of comfort, GORE-TEX® membrane is combined with carefully selected materials for the lining and uper. Your feet are always dry and remain in comfortable surroundings. Gore-Tex® Performance Comfort Obuv s podšívkou Gore-Tex® Performance Comfort je ideálna pre široký rozsah klimatických podmienok a vonkajších aktivít. GORE-TEX® laminát obsahuje vrstvu s miernou úrovňou zateplenia na zabezpečenie dlhodobého maximálneho komfortu pri nosení a optimálnu celoročnú ochranu pred chladom a vlhkom v miernych podmienkach. Gore-Tex® Insulated Comfort Obuv s podšívkou Gore-Tex® Insulated Comfort je ideálna pre chladné podmienky a zimné vonkajšie aktivity. GORE-TEX® laminát obsahuje vrstvu s dostatočným zateplením na maximálne udržanie tepla garantuje, že chodidlá ostanú suché, v teple a v komforte aj vo veľi nepriaznivých podmienkach Advantages GORE-TEX® membrane contains up to 1.4 billion micro pores per 1 cm2. This huge amount of micro pores provides extraordinary one-way transmission. Impermeability Your feet are always dry Special sealing seam, which remains robust throughtout the products life. High hydrophobic properties of all parts of footwear. The legs always remain dry and also in comfortable surroundings. BREATHABILITY We guaranted with the specific cemented process and the type of adhesive: Footwear is optimized for air permeability from inside steam and air to outside. The high requirements on permeability are applied to all parts of the product. The accumulation of heat is reduced. Quality The high quality products with GORE-TEX® membrane is based on precision syetm of controlling from the prototype to the final product and you can be sure in any situation. Not only the membrane but all of the parts on the boots and whole construction is aimed on high performance during using the boots. In each step of developing the product and also in final production, it is essential to check and test many times every technical process. Testing of Impermeability The boots with GORE-TEX® membrane have to endure more than 300 000 flex-cycles (equivalent is 300 km of walking) when immersed to the ankles in water for 80 hours while the pedaling speed is around one bend shie for a second. The inside of the boots have to be clear without any sinfle drop of water. Norm EN ISO 20344 requires testing the boots only 1000 cycles (80 minutes) and allows to penetrate inside 3 cm3 of water. Testing of breathability Breathability is important for keeping feet in good condition. Compared to the standard EN ISO 20345/47, GORE-TEX® materials reached breathability to six times higher. Testing of durability Uppers lining and GORE-TEX® lining must withstand up to 4 times more of scratches as specified by the relevant standard EN ISO. All components have to pass tests before using such as absorption capabilities and the ability to transmit water vapor. Test material quality Manufacture of footwear is process where we can use only the membrane which can impervious water under pressure of 1 bar at least 5 minutes. It can also be used only those components which vapor transmission ability is at least 5mg/cm2/hour. The minimum value is 6 times higher than the standards require. Comfort in all conditions The test of comfort measures the duplex throughput of the shoes. Test runs simulation of sweaty foo inside the shoes at specific temperatures. The final level is calculated on the degree of evaporation and absorption of water vapor. Test site with s priesakom vody 2% of the daily production (or min. 3 pairs of every hour) is randomly tested for possible soaking by filling shoe with water than placed into a centrifuge where are the shoes rotating in speed 240 rpm half hour. The prototypes are tested more than hour. Water must not get out. This is the process when we are sure that the shoes are ok.
