These flips last a long time....reasonable comfort, the materials are meant to last a long time and handle some hard use....I have gone thru 3 pairs over about 8 years, they are all still wearable, none of them have failed, ripped etc.....they have gone up in price to about $60....pretty pricey, but they will last, and the sole will protect your feet from rocks and sharp ground, etc.....I would rely on them as a single pair of flips for an adventure type of vacation where you may be hiking to a desolate beach or something....they are above average in build and toughness. They look pretty cool too....they don't have that Birkentock nerdy feel as some flips with thick soles can look....they are sleek yet tough, not many flips achieve this. They do cost a little more, but they will last for years not months.
