The updated Sirkos Evo GTX Mid Ws, utilises LOWA's proprietary PU in its midsole, to provide excellent lightweight comfort mile after mile. The redesigned panelling on the fabric and suede upper improves the strength and fit of the shoe, creating a low volume, close fit for your foot. The high LOWA Monowrap sole construction provides the very best comfort. Together with the upper, it forms a solid unit, offering three dimensional support for your foot, comfortably cradling and supporting it through each stride on a wide variety of uneven surfaces. A hard-wearing LOWA Cross III sole unit enables good traction on changing terrain, and is energy saving, allowing you to keep going for longer. And of course, the waterproof Gore-Tex lining provides optimal comfort in a variety of conditions. The fit of the Sirkos Evo is naturally a slimmer fit than some of our other models.
