The pinnacle fly fishing boot. Self-draining, aluminum bar traction technology with full length rockplate under sticky rubber. Aluminum plates literally stick to wet, algae covered rocks. No felt bottom means it doesn’t collect and spread invasive species from stream to stream. This was a pet project of Yvon Chouinard and I was honored to work with him on it. The original concept was all bonded rubberized synthetic with BOA closure.
