The story of the Nevada GTX goes back over 40 years ago when Alessandro Marcolin started hand-constructing Crispi boots. The Nevada has been a staple in Crispi’s lineup ever since. Add the latest cutting-edge technology in footwear with the handcrafted precision and comfort we are known for and you get the hands-down best hunting boot on the planet. With 200 grams of Gore-Tex® insulation and a waterproof membrane, there is nowhere this boot cannot take you. No wonder why the Nevada has withstood the test of time and continues to conquer every mountain it faces.(Size 15 are a special build and come with substituted midsoles and outer soles)Gore-Tex® Insulated Comfort Footwear LiningVibram® sole with polyurethane shock absorbing CCF midsole3 Flex RatingABSS Ankle Support SystemBoard Lasting Mechanical ConstructionCrispi Crossbow FrameDual Tech LiningInsulated: Yes - Gore (~200 g)Upper: Water-repellent NubukRemovable Footbed: CRISPI® Air Mesh.
