How it fits?

Recommended Size: Fits As Expected For Most People How do we know? Our MyFit 3D fitting technology leverages millions of 3D foot scans and customer purchases, to accurately provide size and fit recommendations.
Average Arch Height This is the amount of space between the highest point of the mid-sole and the ground. Correctly fitting shoes will take the pressure off your feet as your move, and stop the foot from rolling.
Average Heel Width This is the width of the heel in comparison to the midfoot. A narrow heel will be slimmer than the midfoot whilst a wider heel will be broader than the midfoot. If a shoe is too deep across the instep it can encourage excess movement. If the shoe is too shallow, it will be too tight and will irritate the top of the foot.
Average Foot Height This is the highest point of your foot (called the midfoot and often found underneath the laces) and the ground. Correctly fitting shoes provide stability at the heel and will ensure there is no slipping or irritation at the Achilles tendon.
Average Foot Width This is the widest point of your feet, generally the forefoot. A shoe that is too tight can lead to tension, blisters, and irritation at the ball of the foot. A shoe that is too loose will decrease stability and can encourage side-to-side movement and rolling.




Enhanced breathability provided by the mesh and TPU upper.


Exclusively designed for Merrell, the Vibram® TC5+ outsole provides next level traction for all level terrains. 5mm Vibram® traction lugs shed debris with each step and can conquer wet and dry surfaces alike.


A FloatPro™ Foam midsole for lightweight comfort that lasts, sits ontop of a rockplate for protection against sharp objects.


Bellows tongue keeps out debris whilst a padded collar and a removable PU footbed increases comfort around the foot. NXT treatment prevents odor so you can hike day in and day out.
