When an athletic fit, high-performance, and stellar looks are needed, make sure to grab the Muck Boots Pursuit Supreme Boot. Optimal Flex technology allows the boot to bend and flex with your foot to provide better comfort and stability. 5mm of neoprene insulation and a fleece liner work together to help your feet maintain warmth down to -40 degrees and stay comfortable up to 60 degrees. Spandura is added to the exterior of the neoprene for added protection against wear and abrasion, and the etc sockliner helps reduce friction and heat build-up for optimal comfort. An EVA midsole cushions every step, helping you reduce foot fatigue, and feel more comfortable over the course of the day. The textured grip helps with putting the boots on, and once they're on, the lightweight outsole provides superior stability and support, giving you grip and traction when and where you need it most.
