WTZ – Wolf & Shepherd。This is the weatherized (WTZ) version in size 14, featuring the signature water-resistant full-grain Italian leather, elastic knit bootie, and high-traction \"Toothtech\" rubber outsole. Materials & Construction Upper: Crafted from premium Italian full-grain calfskin leather, chosen for its durability and pliable feel that requires no break-in period. Weather Protection: The \"WTZ\" designation means it is winterized with a water-resistant rubberized mudguard that wraps around the high-contact areas, protecting the leather from wet and snowy conditions. Interior: Features an elastic knit bootie and a cushioned neoprene liner that provides a snug, \"sock-like\" fit while maintaining breathability. Comfort & Performance Insole: Equipped with a removable dual-density memory foam footbed lined with supple sheepskin, designed to provide \"walking on clouds\" comfort and arch support. Midsole: A lightweight EVA midsole provides the shock absorption of a running shoe. Outsole: The defining feature of the WTZ model is the \"ToothGrip™\" rubber outsole. This sawtooth tread pattern offers significantly more traction on uneven or slippery terrain compared to the flat sole of the standard Crossover Mid.
