A hyperlock printed TPU film heel counter, combined with a metal hook and lacing eyelet system, provides a precise heel lock and secure fit locking the foot into the shoe and anchoring the foot to the midsole to reduce in-shoe slippage for quick descents and sharp turns. The Merrell MQM Flex GORE-TEX Women's Walking Boots offer ankle support and extra protection from dirt and debris, perfect for longer hiking days.
