Merrell Siren 3 Women's Walking BootsStay in control with the Merrell Siren 3 Women's Walking Boots. The Vibram outsole ensures supreme grip and traction, whilst the Q-Form Midsole will provide comfortable support and stability.Lightweight Mesh UpperSurrounding the upper of the boots, the mesh is lightweight and extremely breathable. The engineered mesh on the upper has small gaps which allow air to transfer in and out. This will mean that warm air that builds up within the shoe can transfer out of it easily, being replaced by cooler air to keep you ventilated. As you begin to sweat within the boot, moisture is able to escape through the upper. Once it escapes, the material can wick it away efficiently, keeping you feeling dry and fresh. Extremely firm and strong, the boots 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.
