Hotter are not so hot when it comes to durability. We bought a pair of Hotter boots from a reputable store on the basis that this store would provide a reliable source of footwear and discovered Hotter footwear to be very poorly manufactured. The total failure of these boots is both down to the materials used and their construction. The sole is a total shocker as the rubber is simply not fit for purpose and eventually just disintegrates whilst walking. It simply fragments and falls away from the boot. I have NEVER seen such total failure of any footwear and the fact both boots displayed similar construction breakdown shows it is not simply down to a faulty shoe. Hotter is a shoe company to avoid.
