Chelsea Evolution work boots are built for use on dynamic work sites where you need lightweight protection that provides all-day comfort. This concept has been updated with a high rebound EVA midsole and Ortholite® X25 Hybrid footbed for increased comfort. Helly Hansen has also updated the breathable and moisture-wicking lining materials with at least 50% recycled content. The new streamlined design includes reflective details for improved visibility on and off the job site.
