Firm flex insole ideal for mountaineering. Provides rigid support for maximum comfort and stability on tough terrain. Will last the life of the boot without losing performance over time.
Firm flex insole with minimal forefoot flex is to provide maximum support while mountaineering on steep terrain and hard surfaces, especially when carrying heavy equipment.
A Grade 10 Merrell tapered polypropylene insole is designed to meet the most demanding requirements of the wearer while mountaineering by stabilising the foot from heel strike through to toe and preventing excessive foot movement for comfortable walking.
As Merrell’s strongest and most supportive insole, the Grade 10 is extremely hard wearing, immune to moisture, protecting the feet from rocky terrain and will last the life of the boot without losing performance from extended or repeated use.
