Thanks to its great comfort and high level of efficiency during mid-mountain treks and longer walks with heavy load combined with an attractive design and great overall performances, the Spider K is undoubtedly one of our best-selling split suede/fabric trekking models during the last couple of seasons. Its Kevlar upper, protected at the toe by a generous rubber protection, offers great fit and adoption to the foot. Together with the ingenious transpiration outlets at the leg it also helps to create the legendary inner climate comfort of this boot.
