The Men's Simms Flyweight Vibram Boot is a lightweight and durable boot for wading. When walking the river, the grippy Vibram Idrogrip with Traction Lug is the outsole to trust. It's compatible with Simms Hardbite and Alumibite Star cleats and Hardbite cleats/studs, preventing slip and fall situations along the river bed. The TPU-based synthetic woven upper is tough against abrasion, with a molded rubber toe wrap and abrasion panels for additional durability. Walk and wade in total comfort thanks to the dual-density EVA midsole that delivers high cushion and stability.
