So good we Handwelted it twice! It's our Double Don welt, unique to us. The Double Don welt is a new generation of construction of footwear, its been created with the same great features as our regular Guthrie Boots but with some new improvements and some hidden height. The MST Guthrie has 2 tiers of the leather sole and an extra sole edge that is still waterproof and will keep your feet warm in even the coldest conditions. There are two different kinds of Boots, One that performs and one that rocks a statement! This boot has an almighty thicker leather sole and sends a message of quality and uniqueness that hides the insert well. Also looks wicked in black
