Maybe if I did not own other Chaco sandals, I would be satisfied. I live in the southern US and my music has to compete with fans, lawnmowers, and cars on the nearby highway. Because they are so fluffy, youll want to go up at least a half size bigger than your normal shoe size. Very comfortable and great sound guality. The lime green and orange ones are great for safety when walking the roads during low visibility hours. My therapist recommended these shoes. Overall a very nice shoe, that I am looking forward to wearing when the weather warms up. Other than the Powertec logo and the black color of the glide strips, it is exactly like Makita guide rail. God. I bought 6 of these plugs for my 2013 BMW X3 35i.
