I've found that it's surprisingly easy to find clothing and accessories that are up to ethical and sustainable standards, but when it comes to shoes, the pickings are few and far between. There's certainly stylish, handcrafted, responsibly sourced footwear out there -- if you're willing to spend a minimum of $300 on a pair of shoes -- but if your budget is closer to $100 or less, your options dwindle to recycled yoga mat flip flops or ... well, that's pretty much it. Timberland is working to change that with their Earthkeepers line. Made using recycled materials and sourced from factories and tanneries that have shown a commitment to the environment, Earthkeepers are stylish, high quality shoes that you can feel good about buying and wear for years to come. I'm particularly enamored by their summer collection of sandals and espadrilles. Click through to check out 10 of my faves!
