    Perfect shoe

    Shoes are wonderful. Reef customers support is outstanding. We had an issue with a previous pair and they handled it quickly for us. This is our fourth pair (I have two pairs of their sneakers) with the company and we love them.

    Overall Good

    They are comfortable and durable, and are great for being in the water. My only complaint is that when they are wet, the footbed is a little slippery which can create issues when traversing steep or rough terrain coming out of the water. Otherwise I love them!
