Merrell Thermo Chill Mid Waterproof: What you need to know

Interesting takeaways:

  • It uses 200 g of M Select Warm, which provides enough insulation up to the rim of the ankle cuff.
  • Its partly mesh, partly leather upper is coated with polyurethane, giving the hiker even more protection against jagged rocks.
  • The Thermo Chill Mid Waterproof’s rubber panels provide additional side-to-side support, while its arch shank delivers increased midfoot stability.
  • Debris and the like are kept fenced out thanks to its bellows tongue.

A few considerations:

  • On its stout midsole and extra chunky sole (rear part), you might feel a bit too far away from the ground.
  • It does not come with a rockered heel, which could make walking on flat and hard surfaces a challenge to heel strikers.

Merrell Thermo Chill Mid Waterproof vs. Thermo Chill Mid Shell Waterproof

Comparisons within Merrell’s selection of high-quality hiking boots are nothing new, and this head-to-head only solidifies that fact. In the points that follow, you will discover what sets the featured boot apart from the Thermo Chill Mid Shell Waterproof.

Weight. The Thermo Chill Mid Waterproof is lighter than its rival by about 50 g.

Rand. Both kicks have protective randing. That said, the one in the Thermo Chill Mid Shell Waterproof is seamless, hence the ‘Shell’ in its name.

Collar. The ankle cuff of the Thermo Chill Mid Waterproof is contoured, allowing for some lower leg mobility. The competition’s collar, on the other hand, has none, which maximizes support.

Final word: Both hikers in this comparison are fantastic options for winter. That being said, if you value movement more, opt for the featured boot. If you prefer better protection overall, choose the Thermo Chill Mid Shell Waterproof instead.
