A perfect fit means more miles in comfort, and covering water is what the PRO BOA Wading Boot\\\'s all about. Featuring the BOA Fit System this is, by far, the most advanced wading boot ever. The PRO Wading Boot was an industry-first collaborative effort with Michelin, built on an outsole compound specifically designed for fly fishing. This revolutionary new sole design is an industry-disrupting advance in wet rubber traction. The Michelin Outdoor Extreme outsole offers 25% better abrasion resistance and a resounding 43% improvement in wet rubber traction over the competition. Using Michelin tire geometry, it offers a wider footprint for stability, a higher ratio of surface contact, and a lug pattern that reduces shock and improves pressure distribution. The two-layer midsole has a co-molded ESS plate that provides improved stud retention and torsional stability. Orvis partnered with OrthoLite to create a 3D molded X25 insole designed for high-impact sports, delivering maximum comfort and arch support. An industry-first cast PU upper eliminates seams while providing a zoned cage for added stability, grip, and extreme abrasion resistance without the added bulk. The boot is higher cut for ankle support and lined with closed-cell foam. Scratch rubber at the toe cap and heel for abrasion resistance, an oversized heel pull for easier on-and-off, and tightly woven laces reduce broken laces. In shadow. Weighs 50 oz. in size 10.
