- This over-the-ankle version of the Merrell Ontario grants confidence when tackling the outdoors. Its leather upper is lined with breathable mesh for a sturdy yet comfy build. It employs M Select Fresh antimicrobial agents to make it odor-free. 

- The Merrell Ontario Mid’s compression-molded EVA midsole delivers a cushioned ride. It also carries the brand’s Air Cushion (in the heel area) and Kinetic Fit Base insole that provides enhanced stability and comfort, respectively. 

- With a Vibram Megagrip outsole, the Ontario Mid is able to tackle diverse terrain. Its tread design renders ground adhesion.

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.

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. The forefoot and rearfoot areas have a 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.

The Ontario mid-cut hikers by Merrell has pretty much resemblance with the Mountain 600 by Danner as they both feature a classic design. Let's check out their key differences:

Waterproofing. Since the Ontario Mid is made of full-grain leather, it offers good protection from rain or water. However, unlike the Mountain 600, it doesn't have a waterproof membrane which means that water can still get through. This makes the Ontario Mid less suitable for severely wet conditions and more suitable for hiking in the summer or spring. 

Weight. The Ontario Mid is much lighter than the Mountain 600, which is an advantage for hikers carrying a light load.

-The Merrell Ontario Mid comes with an extra pair of accent laces.
-This product also comes in a watertight version, the Merrell Ontario Mid Waterproof.
