Merrell Siren 3 GORE-TEX Women's Walking ShoesStay in control with the Merrell Siren 3 Mid GORE-TEX Women's Walking Shoes. The Vibram outsole ensures supreme grip and traction, whilst the GORE-TEX upper will also provide you with durable waterproofing.GORE-TEX UpperSurrounding the upper of the shoe, there is a GORE-TEX membrane which will provide durable waterproofing. This will mean that all exposure to wet ground or rain will simply rebound away from the shoe, not being able to penetrate through to make the feet feel wet and uncomfortable. In addition to the waterproofing benefits that the GORE-TEX provides, it also allows exceptional ventilation, with warm air able to transfer out of the shoe with ease, which is then replaced by cooler air from outside. Extremely firm and strong, the shoes will protect the feet from any bumps or knocks. The forefoot has especially thick material covering it, which will absorb any bumps or knocks effectively. The heel is held in a secured position, preventing it from moving out of position and causing an injury. In addition, the insole has a Hyperlock moulded heel counter. This will over time mould to your individual heel shape, which will maximise comfort. Up the foot laces with eyelets, and a padded tongue will ensure that you will always have a comfortable and secure fit. The bellows tongue will keep debris out, preventing dirt from rubbing and causing irritation on the ankle.
