This is a nice basic pair of flip flops.  I just replaced my 7 year old ones of the same model.  They were still good, of course, but very worn.  Out of those seven years I wore the last pair, I wore them almost constantly during 2 years of college, that includes winter except when there was snow on the ground.  It also includes peddling my bicycle about 1500 miles.  They are also very comfortable.

I got tired of buying a new pair of cheep flip-flops every year only to have them break a week later, so I figured I would try upgrading to the twenty dollar pair.  It has definitely paid off.  I could've spent 60+ dollars on the cheep ones, so I definitely saved by shelling out the cash for the more expensive ones.  (Well, it's really not a lot of cash, but you'll have to remember I was in college when I bought the first pair).  This would have to count as one of my favorite products, in any category, of all time.

Summary: they are comfortable, they will last a long time, they are worth every penny, and they will become your best friends.
