    CleanStream™ is a design philosophy that runs through 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. 

    The New RIVERTREAD™ platform is designed for the demanding angler looking for the best wading footwear on the market.  RIVERTREAD™ features Simms’ latest engineered components to maximize comfort, performance, and slip-resistance.  The molded 3D footbed with arch support and ball flex aligns the foot for all day comfort and optimizes biomechanics.  Molded dual-density EVA midsole creates extra cushioning for hiking comfort and enhances proprioception.  A Molded and minimal TPU rentention plate allows lightweight cleat retention.  A molded Vibram® Idrogrip® outsole with 4mm self-sharpening multi-directional lugs permits long lasting traction on trails, slip resistance in water and toe protection.  Also available in a 12mm Felt outsole.

    Vibram® soles are built from the bottom up and are designed to overcome very specific obstacles on a variety of terrains. Vibram® invests heavily in research and development of products never overlooking even the most minute detail. Vibram® soles boast innovative compounds and technical sole patterns, specifically developed to meet the challenges of many different environments and applications.
