Danner Vertigo - Mildblend Supply Co。Full-Grain Leather Upper To ensure its quality, we put our leather through six different tests before making our selection. Our full-grain leathers are the strongest and most durable form of leather. Waterproof GORE-TEX 100% waterproof and breathable, GORE-TEX liners ensure that no water gets in, while allowing sweat and moisture to get out. Removable OrthoLite Footbed Multiple layers of varying density are combined for maximum cushioning and support. The entire footbed is made of open-cell polyurethane for better heat dissipation and air circulation. Vibram® SPE Midsole/ Outsole This rubberized EVA midsole maintains the same cushioning properties as traditional EVA, but is more durable and won\'t break down as easily. This technology enhances rebound, comfort and support. Exclusive outsole for Danner featuring XS Trek rubber compound for an optimal balance of durability and traction in wet conditions on the trail or city streets. Non-Insulated Combines our traditional stitchdown technique with cup sole construction that allows the boot to keep a wider platform while eliminating the need for a buffed sidewall. This gives our sneaker boots a modern aesthetic and lightweight, flexible finish. This boot is built on a new great-fitting, ergonomic last. It\'s true to size and has added footbed allowance for stability and greater underfoot support. It\'s easy to wear and comfortable for use in a variety of casual environments. - Worn 2 Times/ Excellent Condition
