I can't even begin to tell you how many flip flops I've found on beaches when doing beach cleans over the years! I've found ones that have washed up, been left or lost whilst people enjoy the seaside! Flip Flops are a real pet peeve of mine for the reason that everyone seems to own a pair yet they are all made of plastic or man-made rubber which causes ocean harming petroleum pollutants to affect the environment! I am SO happy to have come across Waves UK plastic-free flip flops because not only are they SUPER comfy, but they are made from 100% natural Sri Lankan rubber! This means they are 100% biodegradable, 100% recyclable, 100% vegan and are actually made from worn or torn flip flops that are made of the same materials which is something I love! It means that a product that would otherwise have been wasted has been repurposed into something 'new' so it gets another use!
