Servus 12" PVC Polyblend Soft Toe Shrimp Boots are reinforced at critical stress points for improved durability and longer boot life. Using a polyblend injection molded rubber, these work boots maintain their flexibility in cold environments for better comfort and ease of movement on the job. Deep cleat angles on the outsole of these rubber boots provide a secure grip on wet decks, while the FOOT FORM removable contoured insole is cushioned for all-day comfort. Steel shanks provide additional support and stability, reducing leg and foot fatigue.
