The 4" Work Chelsea Boot starts on the outside with a sturdy leather upper and comes infused with CellStretch® technology which provides superior cushioning and comfort through strategically placed cells in the forefoot and heel. The boot features an ASTM F2413-18 M/I/C EH nano toe and elastic gore panels allowing for easy entrance and exit. The mesh lining and leather heel loop add further comfort and functionality, while the Blend85™ footbed, made with 85% recycled foam and ecoTWEED™ lining made from recycled plastic bottles, offers a more sustainable choice. This boot also includes a double-stitched storm welt, nylon/glass fiber shank, and PU midsole, EH-rated oil and slip resistant rubber outsole, and 1.25" tall block heel.
