Sandals seem very tight at first but I wore them for progressively longer periods each day until they loosened up and conformed to my feet.  Now they are extremely comfortable.  They seem durable and my son says they are the best sandals out there.  The only reason they are not 5 stars is the footbed is a little slick but my son said once they wear in a little more that goes away. This is easily the best pair of flip flops I have ever owned
