Soft to medium flex insole for comfort and stability during light hiking and trails that will last the life of the boot.
Merrell’s Grade 4 insole is designed to precisely match the design requirements of a light hiking boot by providing the ideal amount of torsion rigidity and forefoot flex. In this case, a soft to medium flex allows for comfortable movement for trail walking.
A Merrell tapered injected nylon insole is built to protect the feet from stone bruises while being unaffected by moisture. The rigidity of the insole also helps to stabilise the foot during and after heel strike, promoting forward roll from heel to toe for more comfortable walking, even on uneven terrain.
