From high-elevation rivulets to coring into no-man’s land with nothing but bear mace and Ramen noodle rations, Simms’ new Vapor Boot gets you into the thick of it—faster. Its lightweight, minimalist design is maximized by a VaporTread™ platform/4.0mm Vibram® Megagrip rubber outsole that effectively bridges the worlds of superior hiking speeds and traction-enhanced wading performance. Features include a synthetic leather, textile, and scratch rubber upper that, combined with an anatomical top collar, work with your feet for all-day, blister-free trailblazing. Internals are precision lined with plush neoprene where it counts, generating warmth, redefining comfort, and guaranteeing on/off ease whether it’s time to rally—or rest—your dogs.

  The New VAPORTREAD™ is designed for the adventurous angler looking for an innovative piece of footwear that is both trail-ready and wading-ready perfect for accessing remote, prisitine backcountry fishing holes. The molded 3D footbed with arch support and ball flex aligns the foot for all day comfort and optimizes biomechanics. A molded TPU heel clip secures the heel and adds lateral stability for all day hiking and wading. The molded dual-density EVA midsole creates additional cushioning for hiking comfort and enhanced proprioception. Trying to reduce weight for the trail a molded, minimal TPU retentioin plate was hidden between the midsole and outsole to provide light weight cleat retention and to enhance proprioception. For long lasting traction on trails, slip resistance in water and toe protection, a revolutionized molded VIBRAM® IDROGRIP® rubber outsole with 4mm self-sharpening multi-directional lugs was created.

  CleanStream™ is a design philosophy that runs through the Simms line of wading footwear. While not specific to a product feature, this designation does indicate that the product includes features and/or materials that are more resistant to "hitch-hiking" organisms – have less exposed stitching, fewer ridges & pockets and utilize non-absorbent materials – all making the boots easier to inspect, clean and dry faster. All of these elements assist anglers in doing their part to prevent the spread of invasive species.
