crocs started with its world-famous sandal, but has now added a new twist in the Tideline slip-on. It features the same water-friendly croslite material as the original, but this style includes sturdy fabric panels and loafer-inspired style. Comfort stays key, and is even enhanced, thanks to vents around the forefoot and elastic gores.

I got these for a friend who loves Crogs and after he wore them for a few minuets the back of his heel was blistered and bleeding. They were hard to wear at first then he found they had a hard piece of plastic or material right at the heel so he took a pair of tweezers and fished out the hard piece(no cutting needed) and they have been perfect ever since!
These shoes are quite comfortable to wear, light yet supportive. They have two drawbacks: 1. They come only in a single width and 2. are too difficult to get into.
