Most miles of any non-distance running shoe I've owned. Tough Mudder 5k, Spartan Sprint stadium, Super mountain, Havasu Falls, Grand Canyon R2R, and a fair amount of miscellaneous hiking and training. Breaths while keeping  light water out, sheds internal water after submersion quickly, and has stayed tough and together through all kinds of abuse. Massive grip, with very resilient tread-wear. This shoe is a tough performer.
