Purofort® is a unique Dunlop® material with millions of evenly distributed air pockets.
The air pockets generated in the mixing process of Purofort material mean that boots made using Purofort® are up to 35% lighter than PVC, rubber or competitive PU boots. As well as providing thermal insulation down to -20˚C.
Due to the cross-linked structure Purofort® is extremely flexible and offers maximum stretch, for comfort and a longer life-time of your boots.
