Excellent ground adhesion

The Merrell Ontario Mid hiking boots use a Vibram Megagrip outsole. Its 3 mm deep lugs provide ground adhesion on various types of terrain. The triangular studs placed across the sole yield multidirectional traction and prevent muck build-up.

Lightweight and shock-absorbing cushioning

Promoting a cushioned and stable ride is a compression-molded EVA midsole. This lightweight element comes with the brand’s very own Air Cushion at the heel that helps absorb shock from ground impacts and provides steadiness over rugged terrain.
