The Arctic Sport II Tall Boots, from The Original Muck Boot Company, will keep your feet warm, dry and very well protected in really cold conditions. They're fully lined with 5mm neoprene, with a stretch-fit top-line binding that seals the heat in whilst keeping the cold out, and a cosy inner fleece for extra warmth. Underfoot you have a lightweight EVA midsole for added comfort and support, along with a rugged, grippy sole unit that gives you great traction.100% WaterproofFully lined with 5mm neoprene for flexibilityFleece lining for warmthLightweight EVA midsole for added comfortRugged outsole for gripPull-tab for easy on and offEstimated boot height: 43cm/ 17.6"_Estimated max calf circumference: 38cm/ 15.5"_Half sizes order up
