Supreme hunters need a supreme hunting boot. Pursuit Supreme delivers maximum stability, comfort and warmth in a lightweight, athletic fit, that looks as aggressive as you are. 100% Waterproof. Fully insulate with 5mm NEOPRENE. This provides the optimal warmth, comfort, and waterproofing that you expect from a Muck Boot. A fleece liner is added to keep your feet warm in down to -40 degrees. We've added Spandura to the neoprene for added protection against wear and abrasion. OPTIMAL FLEX technology allows the boot to bend and flex with your foot to provide better comfort and stability. EVA midsole cushions with every step.
