Bought  these as a gift for my wife to replace a like model that  wore out. She really likes this pair as they have a longer wearing some than regular  crocks. They do pick up some small stones in the grooves of  the tread. She walks through  the neighborhood and dirt trails that surround our home in N.M and says that they work great in the sand giving added traction. They pretty much fit as expected and like the neutral colors that blend well.
