The Women’s MOAB FST 2 Waterproof Hiking Shoe by Merrell secures your foot on the trails and provides comfort and grip. The leather-mesh upper sports a bellows tongue to keep debris on the outside. Waterproofing comes from the impermeable membrane. The insole is contoured and flexible, with support coming from a molded nylon shank. The air cushion heel provides stability and lessens impact. A Vibram outsole grips to varied surfaces.
