  • This model is an updated version of the Thermo Rogue boot. It has a different lacing system known as the BOA Fit which consists of a micro-adjustable dial, durable lightweight laces, and low friction lace guides.
  • It’s equipped with the Merrell exclusive Vibram® Arctic Grip All-Terrain outsole that is long-wearing and highly resistant to abrasion.

The Merrell Thermo Rogue 2 Boa Mid GTX men and women hikers are mid-top models featuring the BOA Fit technology which gives you the freedom to customize the fit through a simple dial-in system. There’s also a clasp band around the cuff for a secure fit amidst aggressive movements.

This boot uses the Vibram Arctic Grip outsole that “sticks” well on snow and ice. The aggressive lugs are 5mm deep for increased traction on varying surfaces. According to Vibram, the Arctic Grip is their most advanced outsole that features improved grip on ice, cold, or snowy grounds.

For the midsole, this boot features compressed EVA. Compared with other foams, EVA has a lower density which makes it very lightweight. This results in a lightweight shoe that is really supportive and stable.

For added comfort, the boot comes with a removable contoured insole.
