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.
