The Merrell Waterpro Maipo Women's Walking Shoes take on tough terrain with a mesh upper that drains automatically via ports in the micro mesh and antimicrobial footbed. The shoes also features a dynamic lacing system which locks together in a micro-mesh upper and supportive synthetic leather strapping. The Air Cushion midsole provides protection during amphibious ventures, and includes a Q-Form® stride alignment for women. The Lycra® neoprene lining is designed for padded comfort and is treated with an Aegis® antimicrobial solution, keeping your feet fresh. The Vibram® TC5+ Rubber on the outsole is engineered for wet surfaces, with softened chevrons for land and heavy siping for wet surfaces.
