Bottom line

This Merrell mid-cut hiking boot offers readiness on the trails with its provision of warmth and comfort. It was also acknowledged as a supportive and grippy footgear. What makes it most endearing to buyers is its affordability.

However, it seems to fall short on protection against water encounters. All in all, the Thermo Chill Mid Shell Waterproof appears ready on cold, winter hikes; constantly exposing it on slushy grounds isn’t recommended though.

Good to know

  • The Merrell Thermo Chill 6" Shell Waterproof is intended for accompanying hikers on their winter adventures. It features brand-owned technologies: the M Select Dry for waterproofing, M Select Warm for insulation and the M Select Fresh for a maintained cozy feel.
  • An EVA midsole paired with Kinetic Fit Base insole takes care of cushioning and stability. On the other hand, the boot’s outsole, the M Select Grip, renders surface traction.

Merrell’s Thermo Chill Mid Shell Waterproof caters to male and female hikers. It is manufactured in medium width and regular sizes. Generally, it runs true to size. The boot’s lace-up closure permits customization of fit.

With the M Select Grip outsole, this Merrell winter hiking boot gives traction on most types of terrain. Its lugs are 5 mm deep which bite into the ground. The chevron-like boots are adequately spaced to prevent muck from getting stuck, thus maintaining its grip. Its upright extension at the toe area yields extra protection.

Providing cushioning without the bulk is the boot’s EVA midsole. It is a rubber-like foam which grants comfort and absorbs shock from ground impacts. It houses a molded nylon shank which yields underfoot firmness. A trademarked Kinetic Fit Base insole cradles the foot and enhances support.

The Thermo Chill Mid Shell Waterproof is a mid-top winter hiking boot which employs a combination of PU-coated leather and mesh for its upper. Merrell’s M Select Dry protects the user against water penetration while allowing moisture to escape. Also, another brand-owned feature, the lightweight M Select Warm, traps and reflects body heat for warmth.

To maintain the freshness inside the boot, it employs the M Select Fresh. This probiotic technology prevents the development of odor.

A protective rubber shell wraps the base of the boot which boosts its sturdiness. Also, further reinforcement is granted by its durable toe and heel caps.

Preventing intrusion of loose trail debris is the gear’s slightly padded, bellows tongue. Metal hooks, webbing eyelets and a round lace comprise its front closure.
