Patagonia's Reflip Chips are at least as comfortable and even better, they are made from soft recycled materials and are totally recyclable through Patagonia's Common Threads recycle program. The fabric that fits between your toes (what can make flip flops so uncomfortable) is sewn perfectly and is soft and thin and barely noticeable. Perfect for travel, they are super light weight and comfy enough to support some extended walking.
They're vegan too. And did I mention they're cute? They come in three colors, all bright and cheery and perfect for summer. Find them HERE.
