    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

    First, but not last, EVOFIT!

    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.

    Ultimate summertime all around sandal

    Everyday summer time use. Fits like a sock, super comfortable and not as bulky as the newport's, though the newport's are awesome too.
