Description

Keen Utility Synchro MID CSA Waterproof Carbon Toe Metal Free Work Boot 1030644.
KEEN Utility Synchro is a lightweight, high-performance waterproof work boot designed to deliver comfort, protection, and energy return throughout the day. Built with the KEEN.DRY waterproof and breathable membrane, it effectively seals out moisture while allowing airflow to keep feet dry and comfortable. The KEEN.ReGEN+ midsole offers energy return with each step, making movement more responsive and reducing fatigue during long work hours. For enhanced stability, the KEEN.LOCKFIT U-shaped support system provides secure heel control, while a nylon shank adds dependable midfoot support. The boot features a heat-resistant, oil- and slip-resistant non-marking rubber outsole for reliable traction and safety across demanding surfaces. Its fully non-metallic construction allows easy passage through security checkpoints, and the Electrical Hazard (EH) or ESR protection adds an extra layer of safety against accidental electrical contact. Crafted from environmentally preferred leather and engineered mesh with a PFAS-free water-repellent finish, it balances durability, sustainability, and all-day performance in a flexible cement construction design.
