The LOWA Zephyr Mk2 Hi Boots are an advanced version of the original Zephyr Hi boots, offering enhanced durability, technical strength, and unprecedented performance. Ideal for hot and arid conditions, these boots are engineered with a dual-density PU midsole that insulates against both heat and cold. The breathable and tear-resistant split leather/CORDURA upper accompanied by a locking ankle eyelet ensures maximum comfort. The boots also feature a lace holster, instep protection against rope abrasion during fast-roping, and a new outsole that resists slipping, heat, and oil.
