Stiff flex insole for heavy backpacking, designed to provide rigid support for comfort and stability. Will last the life of the boot without losing performance over time.
Built to provide rigid stability and a small amount of forefoot flex, the Grade 8 Merrell tapered polypropylene insole is designed to match the requirements of heavy backpacking for when walkers are carrying extra weight.
To maintain comfortable walking, the Grade 8 insole is rigid to help stabilise the foot from heel strike through to toe, preventing excessive movement with a small amount of flex in the forefoot. Merrell insoles are also unaffected by moisture, will not break down over time and will last the life of the boot.
