This Merrell boot for hiking caters to male and female outdoor lovers. It is manufactured in standard (medium) width and regular sizes. It generally runs true to size. The boot’s traditional closure will allow owners to customize its overall fit and volume.

Merrell’s Ontario Mid uses 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. The forefoot and rearfoot areas have wave-like lug pattern that boosts its grip on uphill and downhill slopes. Additionally, the slight upright extension of the sole at the toe grants extra trail protection.

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. 

A Kinetic Fit Base insole is added underfoot to provide flexible support. It has a unique design that supports the main areas of the foot for comfort. It also allows the muscles to relax, thus reducing fatigue after a hike.

The Ontario Mid from Merrell has a full-grain leather upper. This hardwearing material comes with a breathable mesh lining to optimize interior comfort. At the back of the boot is a leather reinforcement that enhances durability. 

The brand’s M Select Fresh feature maintains an odor-free in-shoe environment. It uses a probiotic technology that helps control the development of odor, especially during active use. 

This Merrell hiking boot has a bellows tongue that prevents the entry of loose trail debris. Its closure system combines metal hooks and D-rings.
