When shopping for hiker Crocs, make sure to consider the weather you'll be doing it in. Depending on your destination, you may want to choose a pair that's suitable for both winter and summer. Alternatively, you may want to go for a pair of clogs that are lined, so they'll be more comfortable in the colder weather. They're also very versatile and you can customize them to your liking.
If you enjoy cereals, you'll probably be pleased to know that Crocs just launched a new cereal-themed footwear collection. The company teamed up with General Mills and Foot Locker to design Crocs based on three of the most popular cereals. The new Cinnamon Toast Crunch Crocs, for example, feature a brown and white marble pattern, evoking the milky color of the cereal. The clogs also feature Jibbitz charms, which you can put in the air holes.
