There's nothing worse than blowing out a flip flop just when you get used to it. I really love Rainbows because they last. I've had my leather Rainbows for 6 years and I can still wear. They look worn out but are still holding up. The leathers are very hard to get on when damp so I opted for hemp this time.<br />I wore them for 6 hours the first day and the felt comfortable from the start. I don't expect to have any trouble but I doubt if they will hold up as well as the leather. I will buy this flip flop again if only for comfort reasons.<br />I will reevaluate at the end of the season.
