Le Chameau has been making boots since the 1920′s. Started by an agricultural engineer, the company usesonly sustainable, eco-friendly suppliers. The rubber is extracted from Hevea trees in the Amazon, and the bark grows back for the process to be performed again years later. Natural rubber means no cracking and years of wear. The calf-leather interior lining forms to your feet over time and the waterproof zipper and buckle top means you’ll stay clean no matter what you’re doing. The best money can buy. $400. BUY
