    More than satisfied with these sandals, I knew I wouldn't be disappointed in Keen. Fits so snug kinda feels like I have on sneakers.

    This is a unique style. It provides the flexibility and feel of a sneaker, but it provides the coolness of a sandel. This is my second pair.

    I have been wearing Keens for a long time. This is now my favorite for warm weather and being around water and trails.

    sharpie to the rescue

    Very comfy and hopefully sturdier than my last pair. But the white sole is hideous. I used a black sharpie to paint it black. It looks much much better

    I've been a fan of Keen, particularly my Newport H2s for years. I recently got my first pair of EVOFITs and love them! They're snug without being tight. A great sock feel with the same great support and cushioning that I've come to expect from Keen.
