This pattern caught my eye because it is so colorful and oh so pretty! If you're in the market for a new pair of the best sandals you'll ever purchase, I highly suggest going the route of the toe strap. It helps to keep my feet from sliding forward when I'm hiking, and contrary to popular belief, it does not pinch your toes.
There are two types of soles to choose from: Unaweep and Yampa.
I prefer the Yampa sole because it is lighter weight with a low profile tread, whereas the Unaweep is much heavier and creates more of a full performance shoe. The Unaweep is definitely the more hardcore of the two options. I do actually have a pair of Chacos with the Unaweep sole, and they served me well during the summer I worked in the mountains of Colorado. I don't wear them as often for the every day simply because of the weight and clunkiness of the sole.
When I broke my foot last year, I wasn't allowed to walk for a couple of months, but when I finally could walk again, I had to wear shoes with excellent arch support. This is where my Chacos really came in handy. They were the only shoes that didn't make my foot hurt with every step. I owe them big time! I am a Chacos fan for life.
