text: While Chaco manufactures their products in China these days the repairs are done in the states. The fact that you can replace soles and straps is a huge selling point for me as the foot bed is the most important part. When you first buy a pair of Chaco sandals you will want to wear them more casually. Do not buy a pair with the intention of hiking in them on day one. The checkerboard pattern on the foot bed takes quite a toll on your feet and needs to be worn in a bit before heavier use. That said, this is my third pair. I wanted to try out the Z2 model with the toe strap. Both the Z1 and Z2 have their pros and cons. I would recommend the Z2 for use on steeper terrain and a snog fit. I would recommend the Z1 for use as a more durable and better looking flip flop (although I have hiked several 8 to 10 mile hikes with no problem at all).
