I like Keen's shoes and I especially like this flip flop with its Keen's trademarked toe guard.  The construction of the flip flop is like any Keen sandal, supportive, form fitting and comfortable.  I even do my indoor aerobics with it because it provides the level of support I need for exercising.  Good value for the money, even though it may seem expensive to some for a flip flop.  My last pair are about five years old and have just gotten to the point that they needed replacing, after being worn extensively here in our warm climate.  Highly recommended.
