    Great Shoe, but...

    These have been some of the most comfortable shoes I've ever owned. The salesman at Fleet Feet wasn't lying when he said you can live in these shoes. I really only get to wear them on the weekends and the occasional evening.
    I wish could wear them at work, but sneakers aren't in the dress code. My only complaint is with the soles of the shoes. On both shoes the grey foam under the ball of my feet and toes has developed several cracks. It doesn't seem to be affecting the comfort of the shoes, but now I worry if I walk outside my feet will get wet if I walk on wet pavement.

    Excess glue and an interior bump in your toe made me give this shoe a 4 star

    Finally! My feet are happy!

    I work outside and spend a lot of time on my feet. Before purchasing Kahru’s Synchron 2.0, the only shoe that offered comfort and support were Chaco sandals. I now have two go to shoes! The Kahru Synchron works with my feet offering a full day of comfort and support. Though they don’t have lug soles, the grippy bottoms of the shoe offer plenty of traction. I love them so much, I now have 3 pair!
