Yet another exclusive item of footwear from Andrew Srl, developed with the help of experts in the field and distinguished champions, for specific use in Fly Fishing in both freshwater and saltwater. Sole with superior non-slip performance on surfaces that are wet, slimy or covered with vegetation (moss, lichen, etc.) typical of dynamic fishing (mountain streams, stony and sandy bottoms, etc.) where high adhesion, stability and grip in the propulsion phase are essential. A mix with elastic rubber that’s extra soft and very comfortable, with controlled deformation. A multi-purpose sole that remains high-performance under a very wide range of temperatures of use, stable on sharp edges, with an elastic behavior. A design that provides for specific seats for easy and precise positioning of threaded studs with a reinforced head to provide extra quality to the overall grip of the sole. Optional version, again available with studs, with a Rubber/Felt mix where the central part is in 100% nonslip polyester waterproof felt.
