Gear Review: Thermo 6 Waterproof Boot Review

Just when I thought Merrell couldn’t improve upon itself, they did. They’ve taken the essential design and performance of a Merrell boot and customized it to fit the needs of snowshoers. The new Thermo 6 waterproof boots were specifically designed for snowshoers yet can be enjoyed by anyone who likes being outside in the winter.

Let’s get right to it. For me the best feature of the boot is the lightweight TPU waterproof shell that is closed molded to the foot sole. Water instantly beads up on the surface like it would on rubber waders or hip boots and has no seam to potentially let in leaks. In addition, it is specifically fitted with flex ribs and ridges to secure a snowshoe strap.

Above the TPU shell is a waterproof Nubuck leather upper with Polartec Thermo 200 gram Thinsulate insulation for warm, dry feet in colder weather. It is easy to plow through snow and sleet with these boots. On the soles are 6mm lugs spread to the edges for a wide range, stable grip on wet surfaces, and the sole itself is made of a snow trek rubber.

Another interesting feature is the heel spikes. This boot comes with metal heel spikes that screw into receptacles on the sole. There are two spikes for each boot to give you the extra traction for those more difficult climbs.

What I like the most about Merrell is their Q Form design for women. It seems like whenever I put on a pair of Merrell’s they conform to my foot exactly. The Thermo 6 were no exception. They were completely comfortable from the first moment I put them on. Even after a couple weeks of “breaking them in” I had no blisters or discomfort of any kind. It was almost as if they had been broken in at the factory just for me.

If you haven’t looked at Merrell, I highly recommend trying a pair at your local store or order on line at These boots were made for snowshoers and I’m sure you won’t be disappointed.
