The Tecnica Women's Viva Mega 8 Ski Boots has a focus on comfort and convenience for the mid-range skier looking for ultimate control in a boot they can ski in all day! The stance is more upright increasing comfort and the Viva M8 takes a targeted approach to fit and performance issues specific to women. Comfort, warmth, convenience and performance are all addressed along with the 70 Flex. The Progressive Cushioning System combines changes to the last, liner and footbed. The liner utilizes a thicker, slow memory ethafoam that offers a very comfortable, cushioning fit. The extra room in the 105mm shell last also allows for a thicker, multi-layered footbed. The result is extreme comfort as well as enhanced shock absorption. The Progressive Flex System provides a flex proportional to the skier’s relative size by modifying the plastic thickness in the spine of the lower shell. This allows a consistent flex throughout the size range.
