Product details:

The Merrell Thermo Chill MID Waterproof Boots combine a waterproof membrane and low-bulk insulation for all-around protection and warmth in wet and cold winter conditions. An M Select DRY BARRIER impermeable membrane seals out every ounce of water as well as letting moisture escape, while a Bellows tongue keeps debris and dirt from getting into the boot and 200 grams M Select WARM insulation provides lightweight functionality. For comfort, you can rely on the Kinetic Fit BASE removable contoured insole for flexible support and EVA foam midsole for stability and cushioning. Additionally, and to ensure expert grip where and when you need it, the M Select GRIP outsole lends durable traction to provide stability in changing, challenging terrain.
