The Prolimit Mercury split toe unisex boot with Thermal Rebound is one of our warmest shoes. Inside the shoe we’ve added Zodiac 2.0 lining to keep your feet warm under any condition. The shoe has a X-grip sole for perfect grip on uneven surfaces. The split toe allows you to have more balance and control. The seams are triple glued and blind stitched so they are extra strong and watertight. The neoprene of the shoe is 3.2mm thick available in color black, size range 36 to 47.
