Product Details
High upper protecting the foot
The raised collar effectively protects the foot from snow and moisture during walks in deep snow. By wrapping around the ankle area, the construction minimises the risk of unwanted elements from the environment entering the inside of the footwear. During winter treks, the high sides are especially useful when crossing snow-covered sections or wading through wet terrain.
Vibram® sole enhancing grip
The Vibram® outsole tread was designed for effective grip on slippery surfaces. The applied structural solutions support the foot while stepping on ice or compacted snow. In practice, this means that every movement on a winter trail occurs with greater control over slipping.
YKK® zip that makes putting on easier
Opening and closing the footwear is efficient thanks to the use of YKK® zippers. This mechanism eliminates the need for time-consuming lacing, allowing for quick slipping on or off of the snow boots even while wearing gloves. In situations where immediate readiness to go outside is essential, the YKK® zipper speeds up preparation for winter activities.

Revelation
My first snow boots and my first encounter with Merrell. A shot in the arm. The boots are great. Comfortable, warm, zipper makes them easy to put on. They didn't get wet in the snow. Warm feeling from the sole when walking. Technically a revelation and visually very nice.
