Michelin’s HydroEdge work boots feature an advanced outsole system that provides the wearer optimal comfort and safety. Designed for use in hot, industrial environments, HydroEdge offers O2F airflow technology, which maximizes air circulation and breathability. A vent in the midsole allows air to move into the boot while keeping water and debris out.Michelin Footwear, www.michelin.com/footwear, (888) 432-7749
