The Asolo Women's Stynger GTX® Hiking Boots are an ideal choice for light hikers and trekkers who demand performance and comfort. With Water-Resistant Suede + Cordura Uppers and GORE-TEX® performance comfort footwear lining the Stynger will keep out the elements. The Duo Asoflex Last is the synthesis of Asolo's research; two elements are melted together to improve comfort and performance. The first element, constructed of a stiff material benefits anti- pronation, anti-supination and anti-torsion. The second element, constructed with a softer material offers shock absorption while walking. The Stynger uses Women's specific material construction in the Duo Asoflex Last. Note: This product comes NEW and in un-used condition, but, may not come in the original manufacturers packaging.
