    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.

    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.
